Best 2020 Chevrolet Silverado 2500 Performance Chips

Absolutely awesome on my 22 l5p!

I love this product. I can change my truck to have to pull the house down or set it up to Canon Ball Run lol

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

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.

Easy plug and play 87 octane tune gives better throttle response and shifts reprogrammed the speed limiter a bigger speed on a Chevy Avalanche and it worked perfectly plug and play install took 10 minutes which was mostly running the cable to the OBD port

I love it and the customer service is the best I’ve ever seen

It works! Seems rather flimsy. To go from screen to screen is pretty complicated. (Although I'm not the most techno Savey person either!) But in the end it did improve my mileage by a solid 3mpg! So that makes it worth having! I have it on an 07 chevy Duramax used for towing, for that it does a good job!

The Edge CS2 won't pull the PID list for my van, so I just get to see the standard PIDs/guages and cannot update to additional PIDs. Not what I was hoping for but it's good with those standard PIDs. Not sure it's worth the price for MPH, Temp, Voltage, and RPMs.

I wanted CS2 to get eyes on my trans temp in my 1997 Ford Powerstroke XLT when I am hauling my camper. When the product arrived (a couple of days before I was expecting) I hooked it up to my computer per the instructions. One easy to follow download and twenty minutes later it was ready to go into the truck. I went out and plug it in (note: the OBDII port on my truck had a black cover on it and was located on the passenger side of the transmission hump under the dash) it would not power up. Hit the trouble shooting guide and it said check the cigarette lighter fuse. Bingo that was the culprit. For reference on my truck it is the #16 fuse which is the fuse in the upper most right hand corner of the fuse box under the steering wheel. So far I have been happy with the product. I have eyes on the trans tempt and new goal to see my truck produce 20lbs of boost (note the CS2 insight is only a monitor and will not help me get closer to this goal but it will let me see it when it happens). I was also pleasantly surprised with how stout the window mount was for the unit. It solid and holds the unit steady allowing you toggle threw the menus with one hand.

Works pretty good. I get a mile to the gallon better. When I tow a 13000 lbs fifth wheel camper it really does a great job. More hp and 1.6 mile to gallon better. Now the truck doesn’t shift gears as much.

Not a huge difference, towing my 28' travel trailer, but I do appreciate the firmer shifts and ability to see more engine parameters on screen. Over all, happy with the product. Easy to install and use.

Bought this for my Silverado 2500HD. After I purchased the tuner add on, it significantly increased my horsepower. Its a difference of night and day. I initially had a problem with configuration of the tuner. A couple phone calls to SuperChips tech support and it was fixed with 3 updates. Etrailer and SuperChips customer service is second to none. I will pay more for my purchases just for the peace of mind knowing a company always stands for their customers

Exactly what I ordered, for to me fast an I love everything about it

Great Parts, Good Price, but pretty slow on delivery.

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.

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