Steven467 Posted July 13, 2017 Report Share Posted July 13, 2017 So I just recently bought an 07 gt500 with 13,700 miles. The car appears all stock besides a short throw shifter, k/n intake, and some trash mufflers that I've already swapped out for KR mufflers. My question is, so far under no condition will the car exceed 6 lbs of boost(by the factory gauge). I live in nc and the temperatures have been anywhere from 90-95 peak and humid. I even tried early morning with temps in the 70s and the results were the same. The car pulls strong, im just curious as I know these cars should make 8-9 lbs stock? Thanks.

08KR525 Posted July 13, 2017 Report Share Posted July 13, 2017 That factory guage is not known to be very accurate. If your really concerned that something is wrong I would install a mechanical boost guage. Otherwise, if the car runs well with no issues I wouldn't worry about it. GL, Duane.
