Car feels good . I was set on 550 rwh at 15 lbs, but got 480 rwh. With the 2 bar map 14.7 is it . I would love to see what 20 lbs would do. Car was falling off at 5700 rpm. Maybe it was cam ? Turbo its a t76 master power with 1.00 ar exhaust housing so i would not think that would choke it up . But 5700 is probably all im going to get with combo. I am going to see if i can get more out of it . I am at the mercy of speed inc. for tuning . I have no clue how to tune sd on gm pcm . But over all happy
