Gearhead talked about throttle balance being a problem with turbo engines. I think this is not the lag which is the problem but the unnaturally high levels of torque that FI engines have compared to N/A engines, though this is more of a problem with turbos than superchargers. Think of it as driving your M3 with and without SportPlus engaged, the higher the revs the less the problem.

Try driving one of those old Group B rallycars, then you will understand what lag really is.

RB26DETT - 8000RPM in the GTR34!!!!! 2.6L!!!! no lag!!!
