how is the project going ? did you fix the Jeep
you need split second FTC1-019B and a fuel pump booster. the factory pump is only good for 7psi and you're 44lbs injector is not a problem.

what? even the tbi pump is good for 14psi and tbi runs way lower pressure than mpfi... unless you looking at huge volume rates

after 7 PSI of boost the factory pump has a hard time keeping up and the wide band starts going lean

ok, so you're talking about boost - it should be fine but a larger pump or a pump booster won't hurt for sure
the guy that started the thread has not been around for some time (on the site). He sent me a pm and he said he got an AEM piggyback for OBDII and that his injectors were putting out too much fuel (probably not at full boost which i thought he was ok for the 15psi), he was also running alcohol injection.

not true.. I run super rich at 10.9-11.3 under boost and  12.3-13.0 cruising with stock fuel pump and 850cc injectors (huge). 40% duty cycle on injectors at 7psi full boost.
