Ditch that ---- and get real fuel management. For the record I wouldn't go above 5 psi. Your fuel pressures will start to go through the roof after that, and you could get an injector failure

I'm pretty sure some of us ran an fmu before we had real fuel managment! Anyways, 5psi, i wouldn't push it any higher or your're asking for trouble!

MY Motec standalone came with a 8:1 fmu and said it was good up to 2 bar.

7 psi all day long on an fmu, as long as you get a high pressure fuel pump, and retard base timing like 3-4* but its sensless, you could have a chipped ecu for the same cost...

Yes, also remember to use some missing link or check valves. You can use fmu no problem, but your next choice must be a chipped ecu and some 450cc, can be cheaper than your FMU and the best fuel management.
