[QUOTE="leforte, post: 360212, member: 1943"] Leforte....if the tune is not tuned for the WI/MI, then an unequal distribution should not make a diff right? if u're tuning for meth and there's an unequal spray, then the risk of deto is there. but with the std tune and tge addition of meth to increase octane, shouldn't this be a suppresant for knock? i'm just curios. with boost and other variables at their defaults levels [COLOR=Red] Meth/water injection increases the octane rating of the air fuel charge in the cylinder. and results in a lower intake air temps of the incoming air charge when injected upstream of the throttle. the car's DME tuning will assume to a small variance that the 6 cylinders are all getting the same intake air temps, the same fuel octane rating, and the same amount of fuel injected into each cylinder and its monitored by two O2 sensors per banks of 3 cylinders. when meth/water is distributed unevenly to all cylinders, some cylinders will be running leaner than others, and results in the detonation of the lean piston.
