Message	Your precision of Control over fuel delivery? I have a similar setup and all though I have not used my boost controller to raise the boost beyond 7psi I have noticed that my injector duty cycle usually is below 10% and peaks near 15%. I wonder if it's harder to fine tune with injectors working at such a low duty cycle. Formerly: Evan3zx(ca) Xbox live GT: kidding Me 1991 CRP TT 1993 Pearl White NA
