3)my car seems to go throught the rpms slowly for some reason. timing has been at 10, 12, 14. i have it at 12 now. fp is at 38 psi. is the 155lph big enough for the 30# injectors i have? trying to figure out why it seems slower. plugas and wires and distributor are pretty new.

thanks

1) When I had nittos I ran 30psi on the street and 20-24 @ the track.
2) I have never heard that before. My brothers points straight down coming off his turbo.
3)30# injectors @38psi=Too much fuel IMO. Try putting your stockers back on and see if the problem goes away.
