550's on a 14b?

[hdswanny]

can i use 550's, afc, and blaha mas on a 14b? with in the next 2 weeks i will have all the supporting mods for a bigger turbo, but will need to save up for one.

in the mean time, i need to learn how to play with the afc so i can get an idea of how to tune. will i be able to lean out the 550's far enough with the afc or should i just stick with the 450's ?

Yes, you can make this work without any problems. As a starting point, install your AFC and subtract about 22% fuel across the board. Your mods don't mention a fuel pump or regulator upgrade. You may have to pull as much as 33% across the board as a starting point if you decide to run 43 psi fuel pressure. 1G's base fuel pressure is only 36 psi, so even though we run 450 cc injectors stock, at 36 psi, they are only putting out around 410 cc. Use that as a starting point and then go through your tuning procedure to fine-tune the RPM bands.

i'll be getting a 190lph fuel pump, but no AFPR.
