anyone running a similar setup, what fmu u running? no, im not gonna do a afc hack, when u mess with the map signal, that throws off the ignition timing, not good on a boosted motor.

im really just looking to get my fuel pressure down, im running stock injectors and a 12-1 at 10psi right now, thats like 160-170 psi. im looking to keep it around 100psi at the most. so i guess that would figure a 6-1 fmu. 6*10=60+40psi=100ish

 

i dunno if you were the same persont hat asked this exact question a few days back, but you dont want to run an FMU with afc hack, thats the whole point of it.

 

I'm doing something simular to what you want to do.
I only have 310cc injectors so i still need the fmu but mine is as follows
rc 310cc injectors
vortec 4:1 fmu
fields sfc.
I have to lean it out from about 5k rpm- 8k rpm about 10-14%.
Works fine for me.
If i were you i'd run the afc hack a lot of people are doing it with good results

 

oh and to answer your question

4:1 fmu and lean it out with the afc even further

 

A couple of people are doing the inlinepro fuel setup which consists of a 12:1 fmu with 440/450 injectors. They're pushing close to 1 bar with race gas on stock motors.

Im NOT going to use the afc hack

Anyways, so i should be fine with 450cc and a 4-1 fmu and an afc to tune it out, correct?
