...what gain (disc/ring combo) do you use for your engine setup? I plan on using the 2.22 diameter disc to support my 550 FWHP combo. What do you think? It will give me a gain of about 2.5:1 and a max fuel pressure of 77.5 psi at 15 psi of boost (base fuel pressure is set at 40 psi).

I've never tried the Cartech adjustable FMU, but I think that the Vortech Super FMU gives you every adjustment that one could imagine. I think they go for about $250 new, but I paid $150 for a used one from the Corral.

TOO MUCH FUEL?

Well I ran the car last night and was very disapointed. My MPH was a whopping 5 mph on the low side (94 compared to 99). Also, the car seems to 'buck' now under light load street driving. I'm wondering if both my SFMU gain and my stock 40 psi are too high for these 38 pounders. Any insight wood be appreciated.
