does timing change afr?if my o2s stay in the 10.5 range, im supposed to tune for best mph correct?so im guessing id add some timing until my mph doesnt increase.my mph sucked at the tracks a couple weeks ago.i didnt have my wideband.thats the only difference now.any more info on what else to tune would be helpful.thankshers my timeslips on this tune,i will definitly work on launch this time.
