Simple to use with easy menus and update process via your computer. Don't expect a dramatic power boost with gas engine. I have noticed much improved mid range throttle response, especially at higher elevations. My 2500 HD no longer has to downshift 2 gears to maintain or increase speed on 5 to 6% grades in winding turns in the 45 to 55 mph speed range. Wide open throttle passes at higher speeds seem to be a bit quicker. To soon to form any opinion on fuel mileage.



by:

Easy to follow instructions, had it installed in 5 minutes. Performance has improved noticable.



by:

Thank you etrailer for your awesome customer service. etrailer will be my go to site for all my automobile needs.

Worked good and came pretty quick

I had to update the tuner two times in order to get the tunes for my truck once I got the tune installed it don’t change my shift points in the transmission my first chip I got back in 2000 changed my shift points as well up the horse power .you would think we’d have better technology in 2021.
I had called the tech line about four times and all the techs I talked to were nice and helpful.



by:

I bought this after installing 4.56 ring and pinion gears in the front a rear axles in my 02 gmc sierra 1500. Due to differences in where wheel speed data is collected between the front and rear axles you'll get an abs warning light if you make any changes in drivetrain bearing. This unit has the ability to adjust the parameters for tire size and gear ratio in order for the ECU to perform the necessary calculations. The result is that the ECU can then realize that both front and rear wheel are in fact rotating at the same speed, which turns of the abs light. I also used a GPS speedometer and adjusted tire size so that the indicated speed matches perfectly a calibrated gps speed perfectly. Its actually more accurate now then it ever was. So I can confirm that this unit will correct both issues you may have. I havnt used any of the "canned" tunes so no comment on performance, towing or mpg gains. Just adjusted the parameters on the stock tune and been running it like that for a year with no issues



by:

This programmer makes a big difference with my 2008 Expedition (5.4 V8, 6 speed auto). Fuel saver mode gave me around 2 mpg better on the highway, Performance 91 gives it a great snarl and significantly more power. Regular 87 mode, after a day or two, had smoother shifting and less gear hunting at low loads. Feels a little more powerful too. I haven't tried towing yet.



by:

First I have to say that ETRAILER has the absolute best customer service out there. When I ordered this over the phone, there was an error that doubled up everything (glitch in the system I believe). Anyway, before shipping, and charging me double for everything, they called me to confirm that was what I really wanted... good thing.

As far as the Superchips is concerned. It's great. Really unlocked my truck's power. So easy, a caveman could set it up. Tells you recommendations (i.e. in performance mode, don't tow, etc.). Also, for Mac users, the Flashpaq F5 is upgradeable on your computer. Just go to the Superchips website, download the "ignition" software and you're good to go. I spoke with Superchips and they acknowledged that's an error on their website. If you're going for fuel economy, go with the "Performance" mode. I've seen easily a 3MPG overall gain in that mode. It's also the one that increases the most torque and HP. Highly recommend this product if you want something simple that will unlock your Cummins while keeping it safe... and you really can't go wrong by ordering from ETRAILER. Seriously, I have ordered tons from them and they are awesome!



by:

The tunes that come with it are great! However the other functions aren't all that special. The code reader is basic at best. It wont pull any advanced codes, the $[XX] code reader from wal mart does the same thing. Also when I changed the tire size from the stock 27" to the new 33" it didn't load it properly and caused the brake and ABS warning lights to lose their minds and flash constantly. Overall its overpriced for what you get.



by:

Wow! I love this tuner! I enjoy the ability to change the tune from performance to towing in a mater of minutes . I was happy to disable the DOD (cuts off 4 cylinders on light load) and to raise the speed limiter too! very happy!



by:

Not a noticeable gain in any of the modes. I would just buy a cold air intake instead and save your money on this basic tuner.



by:

The Flashpaq seems to be working really well for fuel economy but I haven't tried it with my 5th wheel yet. If it works as good as the service I had from etrailer, I don't think that I'll have any problems at all. You guys were great with keeping me updated on my order.
Thank you



by:

Had an EDGE tuner for my '08 F250 that I liked better. This one is kind of slow to update the computer (2 files, with lots of ignition off/on cycles). I tried the Performance tune and went for a quick ride. Yep, it worked. Loaded the Towing program, we'll see how that works out.



by:

So far I have only used it on the 87 octane tune setting. Definitely an overall mild improvement in performance. Does not kick out of overdrive while in cruise control mode nearly as often. Picked up at least one possibly two miles per gallon.



by:

Really helped unlocking power at lower RPM with heavy trailer load. Easy to use.



by:

Have this on my 2.7 l F-150 for a year and it definitely adds a little kick and it's great to have the OBD feature



by:

I ordered a Superchips Flashpaq for my 02 Dodge Ram 4.7. ETrailer was one of very few websites that was clear in its discription on wheather or not it would work on my truck. The customer service is great and the price was good.



by:

Easy to use, works great. This in addition to cold air induction and cat back exhaust really woke my truck up.



by:

Great fuel economy it doubled my mpg. The performance is great it adds alot of extra power. Havent tried the towing yet but if i have no dout that it will work just ass good as the rest of the of them. Thanks alot.



by:

Truck works better with it. It’s an incremental improvement but noticeable.



by:

Took about 10 mins for the PCM to upload the stock tune then about another 5 minutes to program the Fuel savings tune, I could almost instantly notice a difference. I drive a pretty steep hill on my way to work and always have to downshift and lose speed near the top, not anymore I can take the hill in 5th and Speed up as well. 20 HP doesn’t seem like much but it makes a huge difference. Next text will be when I tow my RV to the coast on the heavy towing tune.



by:

Product arrived on time. Works as advertised. Easy plug and play type interface. Like being able to change my trucks program as I see fit. Would recommend to anyone that likes tweaking cars and trucks.



by:

The superchips f5 Flash paq is horrible it did nothing for my truck but make it lose fuel milage even with economy tune i would not recommend this product to anyone

See what our Experts say about this Superchips Performance Chip

  • What is Needed to Increase Torque and Horsepower on a 2003 Ford F250 Super Duty Crew Cab 5.4L
    The first thing that will increase your torque and horsepower is a cold air intake system like the Airaid # AR401-114. These don't have a specified amount of increase in those areas for your 2003 Ford F-250 but it is the thing to add. This will need to be cleaned periodically with the solution # AR790-554 and we also have replacement filters # AR701-445 if you ever need to replace yours. The next thing you can add to boost your torque and horsepower is a performance tuner. I recommend...

  • How Difficult is it to Set Tunes on the Superchips Flashpaq F5
    We don't have any videos demonstrating the Superchips Flashpaq F5 # SU2845 (Or # SU4845 to be California approved.) but it's fairly easy to use. Setting tunes is literally just a matter of choosing options from a menu and making the changes you want to make.

  • Estimated Power Gains Using Superchips Flashpaq on a 2003 Ford Explorer XLT
    Superchips estimates that the Flashpaq # SU1845 (or # SU4845 for the California approved model) will provide up to 20 additional horse power and 28 feet pounds of torque at most on a 2003 Ford Explorer with a 4.0 liter motor. That might not seem like much but you will be able to tell the difference. Gas motors can get small power gains like this but nothing like what diesel motors can get. But programmers are still useful on gas motors because they can help it run more efficiently.

  • Does SuperChips Programmer part # SU4845 Fit 2016 Ram 1500 with 5.7 liter Hemi
    The great thing about the Superchips programmer part # SU4845 is that it can fit several vehicle manufacturers. So the tech you spoke with is technically right, but at the same time the programmer also does fit your 2016 RAM 1500 with a 5.7 liter Hemi.

  • Recommendations for Horsepower and Torque Increase On 2003 Chevrolet Silverado 1500 6.0
    We do have a product that will help increase the torque and horsepower of your 2003 Chevrolet Silverado 1500 6.0, but the Edge Insight CTS # EP84130 is not equipped to do that as it is not a performance-enhancing device. It provides the driver with various vehicle data only. For a product that will provide the gains you are looking for, I recommend the Superchips Flashpaq F5 Performance Tuner # SU4845. This product is pre loaded with performance enhancements such as increased throttle...

  • How Much HP and Torque Can the Flashpaq F5 Give a 1999 Ford Super Duty

Please note that this is not legal to use in the state of California. If you do live in California then we have the Flashpaq F5 # SU4845 which can increase your HP 65 and your Torque 115.

This tuner when installed on your truck can give you up to 26 more HP and 34 foot-pounds of torque. It does feature user-set calibration inputs like speedometer correction for tire size and axle ratio along with adjustments for shift points, firmness, and torque management.

The Superchips tuner is a hand held unit that will plug in to your vehicle's OBD-II port. The Superchips tuner includes tunes for economy, towing, daily driving, and extreme performance.

The Flashpaq works well with vehicles that have additional enhancements such as cold air intake. If you want to have a monitor then the Edge Evolution with color screen # EP85350 or with touch screen # EP59YR are fantastic options. They just are not legal in California. Any of the above programmers will have various modes for different situations...

However, we carry a California approved performance tuner for almost every vehicle that we offer a standard performance tuner for and most of the time they contain the same tunes.

    The Superchips Flashpaq # SU4845 and Edge EvoHT2 # EP86040 are essentially the same tuner just with a different look. Both companies are under the same parent company umbrella. Both are approved for use in California, and both have pre-programmed tunes, one of which is specifically for towing. The pros of both are that they are hand held so you won't have to have either one permanently mounted. Despite being small each is packed with features.

  • Does Superchips Programmer Void Warranty of 2016 Ram 1500
    Installing the Superchips part # SU4845 will not void the factory warranty on your 2016 Ram 1500 under most circumstances. Consumers are protected by the Magnuson-Moss warranty act that states, in part, that unless the part added actually causes a problem, then installation and use of the part will not void the warranty. We recommend removing the programmer before going to the dealer for any warranty work just to prevent any possible issues. Most dealers won't mind but some can be difficult.
