Did you have a check engine light for the o2 sensor? If so then they had to turn it off.

Can it effect your gas mileage, not really as long as it's tuned to 14.7:1 during cruise. If it wasn't then yes it will effect gas mileage and emmisions output

again a simple google search could solve all your problems not trying to be a dick but look up stoich a/f or o2 sensor. This took me 3 seconds

who tuned it?



I figured this was something specific enough that I wouldn't be able to find it on google, thats the only reason i posted here instead.

Import Experts did the tune. I really think it runs a bit rich when not at WOT though, but i dont know for sure. I only say that because I can smell the atomized fuel mix coming into the cabin a little bit when the engine is on the cooler side. And the tuner also said he usually turns them off anyways, so its one less thing to deal with during the whole tuning process.
