Pushing limits of 600cc and OEM MAP? Is 13psi achiveable?
You are going to see closer to 13psi at ap2 redline with a 3" so keep that in mind. SOS isnt very accurate on their website. What size pulley you running now? I would be concerned that your 600cc injectors wont deliver the fuel you will need to cover a 3 pulley. You may be able to cheat with upping the fuel pressure but you really are pushing it, not sure that will even do it. I would go with a 3.4" or 3.2" max. I would also pick up a greddy pressure sensor and run that instead. You will get a better tune.
Hey junky, I am at 3.4" and I Hit 9psi right on the nose, could very well be 10Psi if I hit fuel cut.
I am at exactly 80% Duty Cycle already, I know I know.
I just don't want a complete retune.

I ended up doing the following:
- SOS NOVI1000 3.2" Pulley
- Achieved 11PSI right on the dot.
- Stock MAP sensor held up just fine
- Injector Duty Cycle is at 87-89%
- Belt slip was an issue and it had to be he-man like tightened.
- Tune is conservative.
Final Numbers were 350HP and 230TQ
- SOS NOVI1000 3.2" Pulley
- Achieved 11PSI right on the dot.

Thank man. DynoJet
The 3.4" to 3.2" pulley upgrade yield some nice gains btw. The car loved it. 3.2" gave nice boost across the whole power band. 6K+ obviously is when she moves out.
Here is 7psi to 9psi bump DYNO, so until I get the new DYNO printout use your imagination guys to picture power bump across the power-band.
