I bought the Roush Phase 2 kit for my 2014 F150. It is being installed in the next couple of weeks. The kit comes with an 80mm pulley iirc. How much hp would be gained by switching to a 75mm or 72mm pulley? Reading the pulley descriptions the 80mm pulley should be right about 10psi. It lists the 75mm as bumping to 10.5psi and the 72mm as 11.5psi. What roughly would these translate to in hp and would I have enough fuel for them? The kit also comes with larger injectors (47lb I think) and I have a booster pump as well.
