okay...added the nonsupercharged block to my car and now have nothing but problems and im hoping one of you guys have a solution cause im at wits end. put the heads and gen v on and the car runs like crap..first it wont let me run a case learn. hptuners start the procedure then states that the rpm is too high regardless of the rpm or it just goes back to the start test position. the car is suppose to hit 10.5 aft at 30% throttle and when it does even at 31 percent half the time ill hit a 10 on the knock scale. my wideband is telling me that i am in fact running the 10.5afr so im not lean. the computer is also running a o2 code with a new o2 sensor and a misfire code. plus i now have far less power with the high compression motor then i had with the sc motor which makes no sense. so far ive replaced the crank sensor, balancer, all wiring to ignition, ignition modular and all coil packs, cam sensor, and map. everthing seems fine other than that and she will fun very lean at idle when cold and act like a vac leak whith none present. shes normally getting around -5 on the o2 under most driving condtions...please help as i dont have a clue
