how much boost can meth allow you to run
im wondering- i wanna see how far i can take the stock fuel system on this 4.3L without having to go with MPFI- no one has really ever tried- wanna get 13psi- i plan on running 11psi just on adjustable FMU, fuel pump, and speed density tuning- do you think 2 or 3 psi is conservative or just right?

I am not sure how much boost meth will let you run but it will be important to log and tune for it. Watch for IATs, KR, InjDC and AFR among the PIDs you plan to monitor such as TPS, Spark and RPM.
The chart I have says a M10 Nozzle has a flow rate of 0.187GPM and a M15 Nozzle has a flow rate of 0.25GPM with the small pump.
I am running a M15 with an initialization of 40 psi at 1.5 PSI of boost and a gain of 4 on an AlkyControl kit. The last time out I had my commanded AFR set to 11.5 at 12PSI boost and I was getting an AFR of between 10:1 and 10.5:1. I need to pull some fuel but I am trying to figure out a KR issue I am running into that I think is from TCC lockup. I still need to see if I can tune that out first.
