My boost is around 6-7 like yours for normal driving. Acceleration is 10-14 pounds of boost. Is this too much? Could this extra boost be hurting my fuel mileage? Also, my Trooper does smoke more than it should (diesel smoke). It smokes some at idle, but sometimes it looks like a mosquito sprayer. It always smokes on acceleration. What could cause that and would this also hurt the fuel mileage???

Thanks, Dana
