I just installed a GM TBI setup on my 360 it has a RV style cam and minor mods as well as an HEI Dizzy. I got it running but it seems to idle fine but when I rev up the motor it sounds like it is missing. If i put it in gear and try to drive I have no power at all i cant get above 25mph. I was having back fireing issues through the TB at first running off the computer for timing. I no longer have them as I am running the Manual and vacume advance with the bypass for the timing unplugged. My fuel pressure is between 9-10 which I think is a little low but the injectors seem to push plenty of fuel. Would this cause this issue? Or is it simply a programming issue? Has anyone else done this or have experience that can figure this out im going craz
