i am interested in 5.4L 4v Navigator swap with sullivan intake in a 99 GT any one know of N/A numbers a setup like this produces my guess will be around 350-375HP and around 400ftlb off the crank i would love to see some ones dyno N/A of a setup with this intake.
also what would be better to...
Hi, I replace the stock 99 gt pump with an airtex unit that flows more
Gallons Per Hour: 65-75
Pressure Rating: 100-120 psi
dose this affect my air fuel ratio, do i need a tune.
