Go back to tuner school 12.8-13.0:1 is the norm for NA stuff heck factory the car was 12.5:1 also the car was logged on the road and was pulling any timing also if you add torco the car will automatically add timing just ask your tunning guru LundNo matter what you day man, your A/F was dangerously lean even for n/a. If you were tuned on the ragged edge with decent gas, then what happens if you get some bad gas and the knock sensors are not getting the #8? Kaboom. This was caused by the tune that was made in optimal conditions. Out on the road is sometimes not optimal. My advice for anyone running a tune like this, would be to run a can of torco with a full tank of gas for added octane and safety. Better to run rich then lean and then this happens. I would ask my tuner to pull the a/f back just a tad. But you better have an ofroad mid pipe or you run the risk of clogging the cats.
Yeah, I would stay away with the amateur tuners on this type of high compression motor. Stick with the lund tunes, and make sure you get your A/F checked on a dyno and not just trust the mail order tune is good. Not all cars are created equal.
keep on talking about what you dont know the lund tunes fora bolt on NA 11 are 13:1 WE JUST SPUN ONE UP
