PCM upgrades for pre-OBD2 systems

Folks, I have finally found someone who does programming on GM Pre- OBD2 systems, including the 3.4 V6 !


I'm using a 94 Camaro 3.4 with a 4L60E trans, and he told me he will be able to re-set the lock-up and shift points to suit my car when all the details like gear ratio, weight, etc have been finalized on my end.

I hope this info will smooth somebody's path !

I've been tuning these for quite a number of years. You would have to call me to determine if it's worth tuning. The factory settings are very good and I've heard from a few people who are trying to get more power by sending the PCM in to someone. It usually ends up with problems.

We also offer just about Every part for the L32 3.4L Camaro/Firebird 1993 - 1995 engines, especially in the MGB for over 18 years.
