I have been running a turbo and the MP3 ECU for 2 years now at over 200whp and 8psi with no problems. When I lived in MD, I made 228whp at the dyno event up in NJ at Modern Performance Inc. (MPI).
I run the MPI tuner from MPNick that allows me to control the timing, stock injectors and xtra injectors. If you are planning on turboing it, definatly get an EMS that can control timing. The MPI tuner is $685.
An FMU just raises the fuel pressure to give more fuel, but no timing control. You will only be able to run 4-5psi with that and be "safe".
