Side question: if you can pass emissions with tune and without DP fix, why are some of the MA N55 guys screaming for a DP fix?  |
you don't want to leave it in long term. I had it in for a few months, the car will slowly get slower and run richer. It will also burn more gas. I removed mine and cleared the memory. My next tanks of gas were a good increase in mileage AND the car didn't feel sluggish. You will eventually get a CEL also unless you have a tune (usually when there's huge variances in temperature).
side question: because they didn't buy a N54 to begin with. >=) |
Fighting words bro, haha
