    yeah I'm FI. I sent wheatley a log and explained to him what my guage was reading he's sending me a reflashed pcm. So maybe it'll run better.

    What is your setup? That is a pretty strong output for those bigass tires. Of course I don't put much stock in dyno #'s.

    the set up right now now is machined heads, comp 222/226 cam, vette servo, ported tb, cold air(with out cam useless), single chamber flowmasters, and no cats. 4l80E, with semi float 14 bolt and detroit locker! it suprised everybody on the dyno including me cuss i though it was gonna be around 340ish? but i guess every motor pulls a little different? i think it had alot to do with the heads. when i was talking to virgil i forgot to add in the heads part but its been so long that i didn't think anything of it cuss it was the first thing i did!
