I just got my 88 Iroc it has the 350 TPI completely stock except K&N filters, B&M tranny and 2100 hole shot converter..... my friends have said get intake, exhaust, headers, and then work form there, an otehr friend said to get bigger injectores and a higher pressure fuel regulator.... what should i do, and could you give em some decent parts/prices to go with.... thanks alot guys

well do the "free mods" and tune it up...get it running right. After that i'd definately opt for exhaust mods. For a good exhaust set-up from the heads back, you're looking at $500-1000 (including labor) depending on which parts you buy and how you want to set it up. My particular exhaust set-up set me back $800 and some of my own time (installing the headers), mostly because i had to keep it smog legal which means expensive headers and a cat but its well worth it because you not only gain substantial hp now, but it allows ample room for future mods.

This question is asked on every board over and over, try doing a search.

SFCs, headers and a cat-back.

The stock exhaust is bar far your biggest restriction right now.
