I ripped out all my stock fuel lines including the Evap canister line. I replaced it with a double pumper those feed -6an lines into a "Y" -8an to the rail then -6 to the FPR and -6an all the way back to the tank. The pumps are rewired on a the STM rewire kits also wired in a hobbs switch. I have around 38psi of fuel I activate the 2nd pump by jumping the hobbs switch and it goes about 40psi. SO... I'm getting fuel. But as soon as I hit boost 1psi the car leans out. Its like fuel cut as soon as boost is hit? Im completely lost. I even wired the pumps where they both pump all the time. Still same thing. I'm on FIC 1200cc injectors as soon as it hits 1psi of boost evoscan says I'm hitting 26% injector duty. it spiked at 2psi and i believe injectors hit 30% duty.
