we have a local in SC w/a Dyno-jet & he put's the A/F meter at the exhaust...it should be on the rich side @wot (12.0-13.0) unless you have a vacuum leak,etc...

I live in Tennessee and the closest UpRev tuner is Z1 Motorsports. It's a bit of a trip to get out there and as I said before, I really don't have the capacity to spend the money on a tune right now. In a few more months I will be able to. That's why I asked if it's safe for me to leave the parts on for a few months or if I should remove them and re-install them once I get my tune.
