FMU's and AFC's

[DurtySpeed]

I think a better approach would to be always taking away fuel. You want to properly size your injectors so that you don't end up with too much negative adjustments on your SAFC. How much power do you want to push? <-- start here

We don't know for sure what the future will hold, but.... I just got done doing some reading on pgmfi.org, some great info. The vafc is now ruled out, lol. For now on this motor(d16y7 with 50k) we just want to run 8psi. According to what I read, the hack is only good for up to about 10 psi. That is no good for us as we want to build another motor on the side and and run 15+ in the future. I would rather go ahead and spend my money on something I can use later also. The only reason I bought the fmu is because we were undecided on what we wanted to do and we were running out of time, so I bought it used for 60 bucks and got some check valves at autozone, it is currently set on 5psi. I will leave this until we get the turboedit and get it tuned then for 8-9 psi.

Thanks for all the help everyone.

Well hey its your money or your friends, whatever. The smart thing to do is find out your goal so that you can find the proper sized anything that you will need. How big are the stock injectors? <-- might be able to help you with your baseline tune.
