    How messed up in my tune?

    I went to the track yesterday and was disappointed with the outcome (posted in the strip section). It felt like the truck had no power and my dad said on my first run black smoke was pouring out of the exhaust. On the way home I hooked my diablo to watch the parameters and cruisng on a flat stretch of road at 70 mph/1900-2000 rpm I had low 40* of timing. I gave it about half throttle and it went down to low 30*. Does this sound right? IDK much about tuning, really trying to learn though.

    Thanks dale and virgil, I'm tryin to get my money back from wheatley right now and I'm either going with a Nelson mail order or a dyno tune from speed inc in chicago. I'd love a live nelson tune, even and SD but Texas is just too far to drive right now.
