Most Popular Superchips for 2022 GMC Sierra 3500

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.

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

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
