My GT with only mild mods has a 70mm Edelbrock Throttle body and EGR plate and the stock intake was ported to match. From what i've noticed it's really not bad, but then again with the 3.55 gears it's not often i'm below 2,000rpm. Power really picks up around 2500 and i suppose it helps that my car has the stock MAF sensor to increase velocity (stiffle air flow), which will soon be removed for a larger unit. But I haven't noticed any negative effects like low rpm sputtering or anything else. Unlike a carbureted vehicle, you don't need a strong vacuum signal through the throttle body to help pull fuel... a nice man in a silver box does that for you (the ECU).
