How does it run?

GNO

Iridiums work fine with Forced Induction. Platinum is a no-no, doesn't transfer heat as well as copper or iridium. . . creates a hot spot for pre-ignition to occur.

The iridium NGKs in my Grand Prix lasted longer than any other plug I've tried. Under more boost now, too. Only 1 range colder though. 6 ranges - Where's the gap set at? What's stock?

It runs great and pulls hard. I had the check engine like I said but when we put it on the scanner it was because I don't have a Catlyst on it right now. Idle is fine and everything looks great. I'm going to put a underhood intercooler in it friday just for a little help but still only run 5 PSI once I get the front mount in I will go to 7 PSI. I might keep it at 5 though I like the way it feels right there if I need that extra umph I have the NOS shot which I bumped down to 40. And I will be spraying into the intercooler so It will loose alot of its effect there and mainly be used as a cooler. Once we reset the computer I haven't had another Check Engine. My manifold did crack in one place right where the #3 Cylinder feeds to the turbo. We welded it back for now but we are going to take the Manifold out and reenforce it with more steel and just weld the **** out of it. I used to light a gauge of steel so we need to thicken it up and I'm not about to make another right now so we will lay strips of mild steel on the header and weld those to it grind it down and repeat the process so it will be about 1/4" thick and I will be pretty confident it won't crack then.
