Grand National Turbo on 200 I6

matt1967,
Fuel pressure needs to increase as boost increases. 10lbs. of boost, then the fuel pressure needs to be around 16psi. This assumes the "normal" N/A fuel pressure @ 6psi.
8.5:1 comp ratio will work fine for boost.
Just remember that it takes the proper amount of fuel, and the correct timing to work with any amount of boost.
Later,
Will
