Ditch the FMU?

[Stang_Crazy]

The F150 crank pulley is from a late 80's through 96 5.0 and 5.8 truck motors. It's possible to get your car running properly without a dynotune/custom chip but for safety's sake and to get the most out of your combo, I'd suggest a custom dynotune. You might also want to look into a BTM. The BTM will allow you to run more base timing because it pulls timing out as boost increases therefore reducing the chance of detonation.

As long as your MAF is calibrated for the new injectors, your car should run fine without the FMU. Just set your base timing at 10* and play with the fuel pressure. FP should be between 38 and 42 psi.
