Hey guys. I have a `02 Camaro SS 5.7L Man.trans....The only mods i have are Kooks LT`s & y-pipe hi-flo metal cats ,Magna-flow catback, SLP c.a.i. . Ihave a DS Predator (canned) performance tune in it. Will these light mods have any effect on the running lean/rich? Ive heard so many things about c.a.i. and how they may effect air fuel mixture. Sometimes i also get an occasional code P0138(among others having to do with the 02 sensors) circuit high voltage/heated oxygen sensor. I also have 02 simulators installed. Will a wide band 02 sensor help or will a custom tune be a better way to go? Thanks....

yes, you need a custom tune for the longtubes at the least.

OK but do cai`s make a car run rich?

no, but they can affect the fueling, and its a good idea to do some logging to dial them in.

CAI usually makes you run leaner, since you will be getting more airflow to the intake....
