9-5-1 3 bar and z32 turbo. seeing that guy use the 60 or 65lbs with this program with more f/p. 72lbs is about 760cc, do u think with the 740cc and a little more f/p it would work

I would not see why it wouldn't work.. just put it on a wideband and tune your pressure right. You also have to remember that JWT ecus run rich to begin with.. at least in my experience.

60lb injectors at 3 bar are 70lb injectors at 4 bar. If you have a JWT ECU setup for 72lb, you simply add 1psi more of fuel and you should be all set. You will basically set fuel pressure for 59psi-60psi.

Now, that has NO bearing on the issues you are having. You are going lean because you don't have a tune for the VE. THe map really needs to change when the cam turns over to adjust fuel for the increase in air the cams are allowing by holding the valves open longer.

You can do it stand alone or JWT or Calum or even an SAFC. You just need to add a bit of fuel for when the cams switch over.
