My first race was against a stock supra w/ hoses pulled (Apparently they get like 18psi like that bastards) I ran him at 1 bar at stage say 4 and won by a little (Front of his car was at my door) ran a stock one when I was same way won by a few car's at 1 bar, ran a full BPU me at 1.3 bar w/ what I have now and won he was right at my back bumper.
