    procharged crewcab on 11 psi goes 12.5@113 first time out

    swapped to the 4" exhaust, threw some stockers on it and headed to track

    stock converter is hurting setup but since this truck is setup to be the tow rig the stock converter is staying

    12.5@113 i was figuring 12.6@ 107 so the extra mph is a huge bonus to me

    with swapping to the 4" exhaust the boost dropped and load went back up. prior i seen higher boost but less load as the number was being restricted from the exhaust

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    thanks bud, to me was a new adventure with racing in 4wd and feeling wheel spin. to feel boost ramp in and tires light up and then go little sideways on 1-2 shift as pretty cool

    p1 vs d1 is really only 200 cfm difference. id say still some room left now with the p1 but not going for max effort
