Alright, I ended up with an Adjustable Vortech FMU and Ford red top injectors< they should be here this week some time>

Now ill install these as soon as they come in.

right now I'm running 60PSI fuel pressure on the FPR. I have a 6.5PSI spring in the W/G So does that mean I should be running 6.5x10=65+60= 125PSI of fuel? My math is probably way off but I just wanted to check with you guys.

Now I am getting an OBD-II reader setup for the Laptop in the car, I plan to use this to keep an eye on Boost, A/F Temp and all but I was wondering, the stock Vac sensor can only see a vacuum right? Can i simply swap it out with a different sensor to read boost?

Anything else Im missing?

For clairity heres the list again:
2.5 Charge Piping
2.5 downpipe
1.5 dump pipe
38mm EXTERNAL wastegate(open dump)
Log manifold
T3/T4 42/.48 Turbo
1/4" Oil Feed line
3/4" oil return line
SSQV BOV
Vortech FMU (will start with the 10:1 disk)
Ford Red Top injectors
NGK Iridium Plugs
Intercooled via FMIC

** good choice on the FMU, you won't be dissapointed..


**changes are here**

how much boost can you go up to with a FMU

Im not shure Ill only be running 6.5PSi for now, after I get a standalone and an MSD ill go up to 8-9

Fuel pressure is determined by a few things... how much power you expect to put out at a certain PSI, what your BSFC is and your intended duty cycle - this will tell you your required pressure. You then do the math to figure out that pressure minus base pressure and vac pressure and boost pressure, then divide by psi of boost.

That will give you the ratio and overall pressure. This is a rough starting point.

As for the map sensor - no you cannot just switch it out. A 1 Bar map reads 0-5 volts from 0 - 105 kpa... a 2 bar map reads 0-5 voltes from 0-210 kpa... the PCM would freak out if you did that.

Good luck.
