Re: Not enough back pressure?
Well i did some research and found that you can infact have too little backpressure. Without the back pressure you get too much scaveging and actuallly suck fuel and air out the exhaust causing a lean condition, killing torque. To conteract you have to have a fuel injection system that can correct for this problem. Im getting a adjustable fuel pressure regulator and see if i can richen it up. If that doesnt work i guess ill get the upr cat xpipe.
