Thanks - same as mine . . .

I'm seriously considering 3.73s or 4.10s for mine. And / or a Circle D converter . . .

Then, it'll need a cam swap, and then . . . does it ever end?????

Course not lol, but man, I just don't seem to get it why in perfect conditions in a already badass track your only pulling 14.2's, looks to me like your down 50HP but your dyno numbers don't say it.

Anyways, Im seriously considering 4.10's. When i was at the track on 17's Traction wasn't even an issue then, we shall see .

That's exactly what I've been bitching about for over a year. There are CCSB 6.2s running mid 13s @ 103 with headers and a tune. Like yours!

I desperately need someone (who REALLY knows these trucks and tuning) to ride along with their laptop plugged in and see what's going on. I'd almost swear it's not going (or staying) WOT, or the timing is fudged up, or the fuel delivery, or . . .

As a matter of fact, the way my exhaust sounds and the way the truck feels under hard acceleration I'd SWEAR that the camshaft timing and/or ignition timing is WAY retarded.

Weird, just plain weird.

Hell, maybe I should run a cranking compression test - maybe my engine has internal issues?

Lloyd do you have a log file of the truck? You could post it up on hptuners and see if anyone can offer some help with it.

I have hptuners but honestly don't know anything about tuning and just use it myself for getting log files. Not sure if it requires a license to log a run or not though.
