  • pro racer question-- mustang 4.6 high compression tune help

    hey guys,
    My car is tuned with prp and i have 3 tunes. 93 octane, 100, and 106. anyway, I have made some mods to the car since the tune. I have added a vic jr manifold, a 6061 plenum and also a custom made very wide CAI. I already have my tunes for the previous set up, which is a 12.5:1 motor huge injectors, stage 3 heads and cams, etc. basically a fully done right forged na motor. My question is this, what variables do i need to change in the tune to take advantage of the new vi jr, plenum and cai? thanks in advance. I am new to tuning, and the previous mentioned tunes were done by an expert.
