I got my Superchips tuner the other day... I had to wait to get my AV back from Pro Comp before I could put the tuner to use. After picking my truck up today, I eagerly jumped right into the plug and play tunning.
Unfortunately, I never had the tuner before the lift kit and 35" tires so I am not going to be able to give an accurate seat of the pants comparison.
Using the programmer is simple. There are 2 types of modes. The first is the programming mode which will download the Superchips settings to the ECM. You are not asked what level of firmness or how much to raise Max RPM. All the performance data has been pre programmed by Superchips for better performance So it is not as flexible as the Hypertech.
The second Mode is Custom Tuning.
Here you can modify settings for gear changes and tire sizes. Also you can REMOVE the top speed limiter. Not Raise it but REMOVE it
Make sure you get some Z rated tires.................
Even with my new 35's and after running the programmer, Acceleration and shifting are pretty solid and the speedo is still right on the money.
All the vehicle stock settings are retained in the programmer. I am told that it only takes a couple of minutes to go back to original stock settings.
I might just un program the truck and drive it for a while to see how it runs with the 35's and factory programming. Then I can see for sure how much of an improvement it is.
My truck is a Z71 with 5.3L and 3:73 gears
