AIR and Rear o2 Question I have 02 Z28 so i don't have an EGR, but i know i have an AIR and rear O2s obviously. I live in Indiana so i don't have to worry about vehicle emission testing. My question is if i remove the AIR and have it turned off will this have any effect on my gas mileage, i think i read a thread and someone said that it did have an effect.
Thanks

AIR is on at the first minute or so after startup and shuts off. its used to preheat the cats if i remember correctly. you do not need it and most people on here delete the system or just pull the fuse for the AIR pump so the system never turns on. and no there should be no drop whatsoever in gas mpg.
It seems that was a dumb question, i found the sticky thread, lol

Mail order tunes are for bigger intakes/p&p throttle bodys/Lts which typically include delete rear 02s/egr/air/&fix you air to fuel ratio. Stall converters/gear swaps.
