I have a 2011 GT/CS with auto that is having some peculiar issues. Got an SCT tuner with BAMA tunes and it misses on acceleration up to about 2500 rpms. It runs fine stock. No DLC codes. 14.5mpg town, 23 highway. I drive the car moderately like I want it to last. Got an MMR CAI and Hushpower axle back exhaust. I have it set back to stock now because the miss is bothersome but you can tell there is a "little" more power and shift points are different and firmer but not 400.00 worth of power by any means.
Any suggestions, ideas. I datalogged in tuner and stock mode and the A/F seems to be about the same in both modes. I am convinced it is A/F probably and maybe should get a dyno tune. These SCT tuners and mass tunes are for the birds I feel.
