    5.7 Procharger issue

    Anyone with more tuning knowledge than me able to take a glance over this? My tuner decided he didn't want to assist and took my $500. I have:
    '12 R/T 5.7
    -Comp 270 cam
    -Ported heads, PSI 1511 springs
    -Long tubes
    -Hellcat injectors (used a Hellcats injector data, idles at 14.5 AFR)
    -P1SC with a 3.3 pulley, (not sure on boost level, I'm at 6200ft)
    -Brisk plugs, 2 steps colder
    -Eagle manifold
    -AEM wide ban
    I used a few tunes on here as a reference but not sure I have it right. I have added a lot of fuel and continuing to add. It can be a little hesitant at 1800 rpm. At wide open I am at 12.5 AFR and my misfires are lighting up like a Christmas tree. Running boost I am unsure if I need to run richer at WOT? Normal driving doesn't seem too bad but once you start to load up on the throttle I get severe misfires. A little unsure if I need to keep adding fuel or if my timing is to advanced. Local shop wants $1,900 to start on the tune, but I am trying to learn myself. Any assistance is greatly apricated.

    What is your spark plug gap?

    I set it to .035 per Prochargers recommendations.

    After doing some research I re-gapped to .028 and that made my issue way worse. Running a two step colder plug.

    Ya, i would be concerned you're running an aftermarket map with stock settings.

    Can you send me a scan of a WOT pull from 2k rpms to Redline? I need to see some data before I can assist.
