wen u do the egr n swirl pot mod wat happens to the two throttle flaps as they are not supossed to be in us do they still run on a vaccum or do they just shut n close wen u hit boost? i just want to know about if they are still under vacumm presser if not i wonder if you can just take the flap out of the middle of throttle body just to see if that frees up the air flow so then u dont have any restrictions at all so that mens that my low down torque n power should be better n also wen i take off from the lights it mit be a bit smoother?
