Hi i asked a question to a dealer around here and i said what do i gap new spark plugs cause i cant find it for the life of me and they said they come pre gapped and you just stick em in.

I race asa latemodels and we always have to gap em cause there never the same any suggestions what do you guys gap em at

also i put a mbrp race can on it will this change how my fuel is burned? ( no comments on the can i know u can lose power just wondering if it changes how the fuel will be burned)

So it could possibly lean my engine out?! im not sure how to adjust the jetting on a efi.... i thought efi controls the amount of fuel no matter what

Replace the can with the stock silencer, the engine will run better.[/b]

I can't see where the can change would effect your jetting. All of the fuel scavaging is through before it gets to the can. When the exchaust gets into the can it's pretty much spent. I have used three different cans on my 580 EXT, efi and they showed no difference in piston wash. The can is basically a sound thing. Ron.
