I too have the 5 psi pulley... Alaska no clue what you are talking about


Got this email from Tone about the fuel pressure regulator:

The stock one is adjustable with a security torx wrench - turn the screw clockwise to increase pressure - the vacuum line from the SC to the regulator already does this to some degree and at WOT with a stock regulator, the VX still runs rich so not sure if it is really necessary. I am using the stock one at this time - your shop can recommend one.

So I will go ahead and tune with the stock one and see...
