2004 Chevrolet TrailBlazer Performance Chip Tuners

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

For your Edge Evo HT 36030, I recommend using the same setting as you would for any of the tuners when hauling a load. I recommend using the "Tow" setting for light load tow.

I have a solution for you, but the Edge Module part #EZD1000A is not a fit for the 2005 Dodge Ram Cummins. Instead you would want the #EP36040 if you have the 325 horsepower Cummins or the part #EP30204 for if you have the Common Rail 24 valve that…

Your Edge EvoHT2 #EP36040 is also a confirmed fit for your 2001 Dodge Cummins. This controller is only able to be used on one vehicle at a time, so setting that tuned vehicle back to stock will allow it to be used on another vehicle. Since he said he…

Hey Steven, you can't go wrong with the B and W Companion hitch part #BWRVK3710. It fits directly to the OEM pucks of your 2020 GMC Sierra 2500 and will give you what most consider to be the best hitch around due to how well it's made, how…

Yes, it will work. You'll just need to cut the Lance 6-pin connector out and rewire it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item #e99011. Here are the individual functions of that Lance 6-pin:…

I can definitely clarify things for you. With the Superchips Flashpaq F5 #SU1545, this device is designed to help calibrate your large after market tires, to read clear trouble codes, adjust your TMPS, and adjust your speed limiter. It does not…

Your 2021 Ford F-150 is going to require the Superchips Flashpaq F5 Pro Custom Performance Tuner #SU1545 as long as you do not have a diesel engine. Your Jeep JK used a different Tuner #SU3571 and cannot be reprogrammed for your F-150.

The big difference between the two SuperChips programmers you mentioned of #SU1845 and #SU4845 is that the #SU4845 has been approved for use in the state of California. Aside from that it's the exact same programmer so you'd need to pick…
