Spiker ran a stock fuel pump on his 10lb turbo setup. Anyone else have same issues that a walbro fuel pump solved the issue?
As for the Jeep pump I have no idea on the specs but I wouldn't think that was the weak link. I'd say injectors, even though Honda's can boost on the stock 240's I do not know what kind of injectors are on the jeep, p&h or saturated.
Sounds like you might have a couple things to take care of, a GM 2 bar MAP won't work on your car?

Re: Not using a check valve on a MAP sensor
You can't just add a 2 bar map sensor. All MAP sensors have a 0-5 volt range. Just changing the sensor will make it run like crap. Lets say my map shows 2.5 volts at idle, A 2 bar map would show 1.25 volts to the ECM. You need to program the computer for a MAP sensor change.
