I'm running the slight mix (16-18%) in 34* - 38* in the morning here. No significant changes in the LTFT, AFR, or FRP...yet. Car is running smoother and pulls harder than it has since we purchased. Quite impressed with what this small dose has done. KR readings are near impossible to come by. An occasional lift reading of .8 or 1 that I still haven't visually caught.
