I have a 2012 mustang gt (auto) the only thing done to it is mufflers I just had a tune put in a month ago and everytime I launch it, it bogs really bad 2.20 60ft normally stock tune 1.93 60ft I have taken it back to the guy and cant really tell me why except maybe the 3.15 gears but why would it do that with a tune and not stock
