[Build Thread] -- Journey to 700+ WHP [Supercharger]

Duty cycle too high... I had Eugene tune my car too, and we never even bothered with e85 because I was already at 80% on pump gas! I have 1050x

I have 1050x and Walbro 485

Is your FPR Working? 442 WHP should not be needing 90% duty cycle. Hopefully you figure that out, but it sounds like maybe your fuel pressure is not raising at a 1:1 ratio.
