Jesse -- 9.6 AFR is a bit fat, you can lean that out and recoup some horsepower. If you're at ~10.9 under WOT at max boost, that's about where you want to be based on my memory from Anthony's best tunes.
Austin -- AFR's in the 16's are DANGEROUSLY lean... like, meltdown area. Don't do another WOT pull until you get your tune sorted out.
Once a car has been tuned does it need to be tuned again. How can tell if a car is out of tune. The mechanic hooked the car to computer turned the key and said the sensor was good. I live in Louisville Ky no one knows anything about these cars.
