hey guys, I have an 04 ba m1 xr6t auto 140k on the clock. when the car is on less than a quarter of a tank of fuel boost comes on 6 psi steady all the way to when the auto shifts to the next gear and boost spikes to nearly 10 psi between shifts but no torque control from the ecu, just wondering if that's normal or not, oh and the only mod is a k&n panel filter. cheers tim.
