well finally somehow my afc v2 started to save its settings with the 450's...anyway, we gave it a basic tune job and i drove it around from 2-4k rpms for about 20 minutes, then let it sit for about 30 minutes, and it was very difficult to get it to start up again....i messed with the settings slightly and it was still kinda tough to get going...

once it idles, it idles great and drives like a dream...but its weird how it has trouble starting...anyone have any ideas what could be causing this
