spark plug question on a turbo'ed car
spark plug question on a turbo'ed car I have what in the sig. below. I run 5-6 lbs depending on the day. I have ngk irdiums tr-55 in the car right now and I see 9.9 to 10.5 on the wideband at wide open throttle. Should i change my plugs to a tr6 or leave them the way it is. right now its always rich I was told a colder plug will make you run more rich.
i run tr6's, no problems so far.

u need ls1edit to lean out your injector offset table to cure that 9.9-10.5 all you are doing is flooding the engine with gas and washing out the rings.
