loud pop
Exhaust leak?
Valve springs?
Tune?
No codes, gas mileage is the same ,no changes on set up,
Thanks
On the way home , I unplugged the mass air flow sensor, and let it run on speed density tune , problem went away immediately , so i will replace the maf,
Glad my tuner took the time to tune it both ways.
Thanks again James Short ( Shorts Tuning)
