In neutral, idle im at 40psi, give it a little gas and it goes up to about 50psi, take it up to about 6k and it drops to like 10psi. In gear, it does the same thing but at 4k if i stay out of boost or 6psi if i do boost. Im running a Y8 with a t25 turbo kit, 240 injectors, 255 fuel pump, aem fuel rail, aem fpr, greddy emanage(very agressive fuel map right now), new filter. Actually all of this is brand new. Hit me up on messenger if you have any ideas, or need more info, thanks. Kolk1 on yahoo or kolk80 on AIM, thanks
