Get the LT4 Knock Module if you want to get picky, and if you have the 1.6 RR's. If you have a good Tuner you won't need to worry about it. If you still have the LT1 Cam in it, then leave the EGR on it. If not, have them completely tune the EGR out of the Computer, and remove it completely off of the Engine.

Chips don't do ****, get a tune..lol

what year is the car? if its a 93, you need a chip, I would have a custom one burned by pcmforless. If it's a 94+, you will really want a custom pcmforless tune still. just have a lil chat with him(bryan), and he will recamend all the best routes for your tuning needs.
