Whenever the fifth injector kicks on my engine bogs down and doesn't want to go anywhere.It kind of sputters, I think I am getting to much gas. I just installed it today and I have some other questions. The installation instructions were a little misleading when doing all the vacuum stuff. Does the vacuum port on the aerocharger turbo run to the switch? I ask this because it seemed like I only got 5 psi when i flipped the switch either way. Is the port supposed to vent into the atmosphere or back to the intake manifold? A detailed report would be great. If you guys can give me any help, I would greatly appreciate it!By the way-AC3 with 2000 mani.
