1. ok i street tune my afr to 13.1 in 4th gear before i went to the car cruise last satuday night the next day i look at my onboard data logging and it show my 2nd gear afr went lean to 13.4-13.6 and 3rd gear went to 13.2-13.4 but it looks okey and my 4th gear was 13-13.2 afr... why is the afr goes lean?
2. is there anyway how u can tell the car is breathing good by just looking at the map sensor reading at datalogging?
pls dont tell me to tune my car on dyno becuase its expensive it can go 1000+ bucks....
