You running 20 psi with a stock intercooler, just curious?
Yes, everything to do with the engine is stock, forgot to mention im running a T3/T2 clutch from FWDPerformance. I was trying to run 25psi during the summer but was continuously knocking on pump gas, so im running 20psi and happy with it.
AF at 20 PSI?
I don't have a wide band so I can't tell you what it is, I'm just using an air/fuel gauge. Don't need the wide band until 30psi ;)

sure don't drowning the engine with fuel so you make 20 PSI HP at 30 PSI :rolleyes:

I would rather not mix fuel with my oil and strain my turbo so hard for nothing. You can add 100 WHP to a new Evo X by fixxing the fueling at the stock 23 PSI. Barely running over 100 MPH in the old days at 30 PSI sucked.
He's using one of Robs cals so its probably fairly reasonable. Were it one of the FWDP cals I agree there would be a lot of power to gain by turning down fuel pressure or similar
rob from boost button are his cals GOOD
