Hello,

My car runs great but I was wondering what affect my bolt on's have had on the air/fuel ratio? This is what I have: ported TB, Magnaflow, Intake, chip, UDP, wires and that's about it as far as the motor goes. I took out my plugs and they are ok (they are light tan like they should be). I was just curious if I need to do anything to avoid possibly running to lean? Or can I just keep adding on a few more bolt on's? i.e. (headers, high flow cat,flex)I hope this isn't a stupid? I just never hear anyone mentioning this topic and was curious.
Thanks!

p.s. The chip advances the timing but that's it

with minor bolt ons (which you have and are talking about adding) the engine computer will compensate and keep you at the "right" mixture. and by the quotes i mean plenty fine for all intents and purposes, but there's probably room for correction. ANYHOO, there's nothing you need to do with A/F for those bolt ons.
