I have a 10% pully, K&N cone on the MAF, 2.5 inch exhaust with magnaflow resonator and 3 inch single pipe with no mufflers. I'm pulling about as much boost as without the 10% and exhaust. I floored it from a stop, and it didn't spin either. Does it need a little back pressure? I have a medical restriction on my license, and I can't remember/can't tell if the car is faster now or the same as 3 months ago. It used to spin a little on the street. Anyone with similar mods, please tell me what boost you pull. thanks
