i purchased the superchip, and just got it in this weekend, waiting until i get the time to install it. according to some people, they are a waste of money (both brands and others), but according to a good friend of mine, who is a certified hummer mechanic, told me that they will help the cars that have the sophisticated computers than others that do not. other mechanic friends said basically the same thing. and others did not. so i decided to try one for myself, just need to install it, thats all.
The reprogramming does make a difference, as the ecu controls the vehicle:
- rev limit
- max speed
- higher shift speed - torque converter lockup.
- different timing
The original chip is designed for max fuel economy and passing emissions
and I have made changes to my cadillac without reprogramming the chips
and it takes a while before the ecu notices; but it does - about I week.
Yeah, playing with the chips does make a difference and Fastchips and Superchips, will also put in some protection too. Read up on it.
