ummm in some cars an FMIC can throw your a/f ratio off so much that it would cause problems... so that blanket comment is kinda null and void.... perfect example are cars that run lean (rx7's, supras, etc). FMIC is just going to benefit temperature. Not going to control A/F ratio's which is the only true way to insure you won't blow your engine.StreakinOraNgeX said:The fmic is the single most mod that prevents premature pings and detonations, I've read that in countless magazines.
If you're wanting to boost 11psi buying a downpipe would be more of a precaution than buying an FMIC. You can buy an FMIC and still be faced with the restrictive stock exhaust issues. Buying a good DP, using colder plugs, higher octane gas, reliable MBC/EBC, or best of all fuel management system is going to benefit you the most.
An FMIC would be a nice addition to any system but there are more vital things when dealing with upped boost.
