Made three runs tonight...

1st run:

60': 2.02 (flashed converter)
1/8: 8.95@79.15
1/4: 13.94@98.32

2nd run:

60': 2.04 (Off the footbrake, ~2800 RPM)
1/8: 8.97@79.15
1/4: 13.96@98.13

3rd run:

60': 2.02 (Off the footbrake, ~2600 RPM)
1/8: 8.95@79.15
1/4: 13.94@98.32

Mods: Headlight pulled, Vector tune, K&N drop in, Yank 2600 stall.

Conditions:

Temp: ~64
Baro: 29.77
Humidity: 100%
Track elevation: 20 feet

D/A: 786 ft. My last run, corrected for DA, was 13.82@99.13

I don't know, I had hoped for a little bit more out of the tune. The DA today is almost identical to the DA on the outing I made right before the tune (within one foot, to be precise, 787 ft).

Prior to the tune, I ran a 14.09@96.92. So, I only picked up .15 and only 1.4 mph? Something doesn't quite add up. Chris, if you're reading this, have you made any changes to the to the cals? I was flashed at the Delmarva meet, the black TBSS with the stall. I got the "no CAI" tune.

I can tell the tune is "there" based on the firmness of the shifts. Also, are you removing any of the torque management because this thing doesn't seem to want to 60' worth the damn. It's almost like it's being held back.

Thanks in advance,

Ryan

Other than the insane humidity, clean the MAF if you have a K&N it's probably oiled to ****; consult fishhunter on that one ;) Also a 2600 converter wont really do anything in these trucks its barely over stock at that point; which is probably why you 60ft like one :) Email me if you have further issues I can give you some troubleshooting stuff to try.
