Hey guys I have a 2010 CTS V A6. Mods are Cold air intake, headers, and full exhaust. Only mods in tune are to remove any rear o2 reports and P1153, P1133. I have been experiencing some hard/ugly downshifts and upshifts on WOT even before the o2 removal. I have logged and found to be getting knock while it shifts and at some points after, hoping its not a mechanical problem and can be fixed with a tune. Im new to HPtuners and tuning. Ive added/removed parameters that I think would help with find out what is wrong, if im missing any let me know and I will log once again. Any help is appreciated. Thanks
