I thought this was not to lose your revs? 3 friends all have s197 stangs and they rev while shifting nt to lose RPMS I though one has a 07 10 and 12, confused because mine started to do this after Tom's tune thought it was all a performance mod? If this is a bad thing maybe I should let him know... and also my friends lol.. The 07 GT really bad at doing this and they're all stock ECU's
