i have a heads and cam lt1 car that has a mail ordertune for madz28. and i am having problems with the way my car is running so i barrowed a predator from an ls1 buddy of mine so i could monator my live data. i am new to all of this tunning stuff so i was wondering if anyone could please tell me what the sensors should be reading. sensors like the o2's, map, ect. that would be so helpful. thanks in advance.
