Headers Custom prom wont start
88 gta 350 I installed my shorty headers, ran mds wires, shorty sparkplugs, removed smog pump and air accessories, installed my piggy back custom tune from hawks. Now it won't run . It will try to start but chokes and dies. How do I reset the IAC and TPS back to stock?

Try starting with just the memcal to rule out a faulty chip or tune on piggyback . Plug wires in the right location?
