have u gone to the COBB website to research?
Stage 1 93 oct - STOCK CAR! no intakes, no exhaust...nothing (however, the only intake that will work is a COBB short ram)
Stage 2 93 oct - full 3" TBE, no intakes, stock turbo, stock everything else
if u have anything other than what COBB tells u to have on, ure gonna destroy ure block. if u want to put other mods on ure car, buy streetTUNER, or find a tuner that has proTUNER. they can custom design a map for ure mods. like csewrx said, DONT SKIP AHEAD! FOLLOW INSTRUCTIONS! AP is idiot proof if u research first.
however, if u go back to all the stock equipment, u can load stg 1, so u wouldnt have wasted ure money.
