Lean or Not ?
Hey guys I drove down to so cal and got a tune on a 91/C16 mix. I drove back to Vegas and noticed a light gray soot on my exhaust tip and was wondering if this is normal from running C16? or do you think its running lean? Im going to pull the plugs and look at them tomorrow, but I read in this thread:
https://www.evolutionm.net/forums/sh...t=running+lean
and noticed someone said that race gas will leave a white/gray deposit on the plugs.
Any ideas of things to look for ? I dont hear the car pinging or anything like that and if feels really strong and smooth with the new tune.
