your car will be fumbling , and runing like shit ... make a dn dn dn dn dn dn sound on the end of your boost in gear chance..... go gap your plugs or check coil packs..

i think i get that at full boost like 12psi (especially when the air is cold.) is the retard or misfire.. basically when the car at the limit at the end of a gear. does that mean im pushing too hard?? is it real bad.. sorry to be a little off topic, ive just always been really curious ever since i got my car

it cud be a number of things. Clean ur air flow meter out for a start. den check ur plugs and finally ur coils. most likely it would just be the plugs but if not new spitfires should do the trick. just be careful, dont push it too hard atm when its detonating..
