From what I understand running 6 psi with the hack is not recommended.

Are you looking for fuel percentage settings or what? What guages do you have? You will need an a/f guage and an EGT would also help.

well i plan on running 10psi when its dyno tuned. right now i just have boost and a/f EGT is comming. I have a MBC thats sitting next to me not installed yet and also a walbro 255lph fuel pump i can install at any point. people are saying run -38 which i was toying around with on the street earlier trying -36 and -40 and it was hessitating al over and when i WOT it was bogging/hesitating but tomarrow i'll try -38 and any other suggestions people can give.

1) Do blue wire mod so you can monitor O2 volts under boost. Aim for 0.900+. That is not in anyway accurate, but you should be safe. Check your plugs to verify that you are not getting detonation.

2) Retard your distributor about three degrees. That should minimize the advanced timing to something you can safely run with a good rich mixture.

3) Your choice of turbo rocks. Pricey when compared to the regular jy fare found on this board, but they lay incredible power down per psi.
