    What fuel pressure is required for TBI? Is EGR removed and does new PCM chip delete EGR code?

    Asked by: 95Z71
    Most TBI engines will require 12 psi of fuel pressure, this is an EGR engine and when you order it you will call Blueprint with you information and they will burn a chip for you.
