Anyone put a computer chip in their yukon..Got a 97 and want 2 get better gas mileage and performance

I can't speak for a '97 but I have a Westers PCM in my '04 DXL and it is the best proven performance gain for the buck.

Hear hear! Tony helpe me with my decision to go the Wester's route. I can't imagine a better mod for both performance and economy.
