the 97-98 pcm is completely different than the 99-04 pcm.

they make a hpp3 for the 98. a friend of mine had one in his 98 z28. using the performance tune cause major spark knock to the point where you could here it. and his car was stock at the time.

save your money and skip the HPP III and get a real tune...

true, get full exhaust and gears, the do a LS1Edit or HP Tuners at a pro shop.
then do engine stuff like cam + heads and do another pro tune.

depending on how long he woul wait between exhaust/gears he probably shouldn't do the tune until after he gets the cam and heads. waste of money. 350$ for a tune then 150 for a retune? talking 500 for tuning right there. I'd rather wait until I got the heads and cam before doing the tune.
