A lot of it depends on what type of fuel you use and what you get your car tuned for. 19psi sounds high for a VF30. I think you could reliably run 18psi on 93 octane with a VF30 and a FMIC. I wish I could get 93 pump octane. Also remember that it is hot in Texas all of the time, so outside air temps will play a big part in your Air/Fuel Ratios. Even with a FMIC and 93 octane.

I have the VF22, and I can only reliably run 16psi on 91 octane with my TMIC and still run safe AF/R's.

There is no need for fuel rails with any VF series turbo.

thank you , you've been the most honest person :D
Just telling you the truth about things that me and the rest of the members here have learned in the last few years. Why don't you ask your brother about these things? Or does he clown you since you drive a 4EAT? ;)
