Any one here have their 97 LT1 tuned? if so, what did you use, how much, and how well did it increse performance? let me know...thanks

 

Can be tuned just like any post 93, which is not programable. 94/95 are OBDI and 96/97 OBDII. I use LT1 edit, and had pcmforless tune, that helped alot in reducing cam surge.
Make a search for madwolf or pcmforless.

 

anyone know the site address for the madwolf tuning?
