tbh getting your car back from MSD transforms the car anyway !!!

paul look into what a closed loop conversion actually does, its for part throttle driving/cruisng on motorways off boost, on boost the car will still be bad on fuel !!!

the remap will affect the way the car drives if theres a bad map on the car ( cossie motorsport chip on greys for example)

my car felt ALOT better when it came back from MSD and it just had a custom chip fitted to it, no closed loop ect, he just tided the fueling and ignition maps and the car performed better !!!
