Default Re: 90 stalling issue solved

Varying the vacuum at the FPR varies the fuel pressure. I used this approach on my 84 Xfire so as to be able to use TBI injectors large enough to feed a modified motor at WOT and yet idle properly. But to do that required code so the injectors metered fuel correctly at all vacuum levels. We don?t have anything like that in the LT5 code.
