Hey guys been tuning my 07 corvette. It's a bit different to tune than the gen 3 cars but I'm getting it figured out. the car is stock other than a catback and just turned over 20k. Even before doing any tuning I noticed the long term trims were uneven. I have got them back in the normal range now because they were running a bit high in the positives with the stock tune. it now runs about -2 on right bank and 0 on left bank. They are still about 2-3 percent different between the two. I thought it may have an air leak at the intake but done the spray test and couldn't find anything. No exhaust leaks either. Runs great but just bugs me a little why these trims are not even. Any idea what can cause this or is this just normal?
