Not what I expected!
Received the unit quickly, as I always do when ordering from AutoAnything. Reviewed the instructions to ensure I didn't screw up my ECU. Waited a few days before installing a new program. The installation was very simple and straight forward. The third day after the upload my truck started running rough and I started to get "Stabilitrak" and "Traction Control" errors. I had to pull over and program back to stock. Still had the same engine and alert issues. Took my truck to my trusted mechanic. It's now been a week, and it will be $4,000 to repair my engine. Trying to determine if the new program also uploaded a virus. Mechanic advised that to change the programing, it takes a more sophisticated unit.
Very simple product with great results
This chip is very simple to use and I have been impressed with the performance it offers, I noticed a big difference when it the truck switches from 4-8 cylinder (not so much lag) and it definitely increased the overall power. I cannot comment on fuel saving since I originally bought this since I was doing a lot more city driving than before but it seems I'm getting about 1MPG better on roads under construction and morning traffic. Overall couldnt be happier
The tuner was super easy and simple to install. It literally took minutes to install. Performance increase is very good with sharper shifts and higher torque The mileage increase is better by a few MPG, but I have a hard time keeping my foot out of the throttle. I would suggest it to anyone that want "bolt on" performance. This is the second superchips tuner I have purchased and these guys know how to do it up right. They will even offer tech help on the phone if needed.
