boggs down at 1500
i'm running a pair of hedman's with no cats and a pair of 40 flows with dumps. it sounds like crap especially when i hit the throttle for daily driving. it leans out so bad on the freeway that i lose all my speed and have to get off onto the acess road. his problem is killing me.
i have no leaks anywhere in the exhaust. i have also learned today that the less backpressure the better. could the exhaust be the source of my leaning out out on ny tbi motor?

Hedman whats?
Did you retain the O2 sensor?
Reports are TBI typically needs reprogramming if exhaust is radically altered. Check out the TBI forum.
