I just got a new Pro-m 80 mass air, morpheus power pipe, 42lb injectors and am ditching my fmu. My question is what should I set my timing and fuel pressure to so I can feel safe driving my car to the dyno machine which is 2hrs away.
Also what kind of Horsepower should I expect with this setup-check out my sig.

The consens for a "safe" tune is to start with 40-43 psi (vacuum off) of f/p and 8-10 degrees base timing. This should be able to allow you to make it to the dyno w/o any problems.

Can I ditch my FMU or is their a way just to dissconnect it from increasing the fuel pressure by unplugging the vacuum line?

yeah with those injectors and 2 fuel pumps you should be A-OK. Do you have a boost sensitve regulator?

It has a vacuum line going to it so I am assuming its boost sensitive. I'm not sure what you mean by boost sensitive. What kind of pressures should I see under boost? Do I have to COMPLETELY dissconnect my FMU?

yeah you can disconnect the paxton FMU. Do you have a fuel pressure gauge mounted in the car? If it is you should see the pressure come up whe you hit the gas, and it'll drop when in vacuum. i think this is right....
