i have a 02 w/ aem intake and hks hiper. my cel keeps coming on and turning off (system too lean). 1st, is it lean enuf to cause ne type of damage to the internals? and im guessing the only way to get rid of it is a safc and dyno time? thanks.
well ud dont really want to have your check engine light on do you?
cuz if anything ever happens to your car that would activate it, then you never know anything was wrong since it would be already on.
you could take a look at the HKS afr that would work as well id think and much cheaper
