This morning I ran a 14.77 at 95.89MPH on the G-tech. It felt stronger then it usually does, but my best before today was a 15.074 at 93.43 and 60ft of 2.365, so I don't know maybe it was a glitch.

I did the run with a cold engine, about 1 minute after startup, and it was only 0-1 degrees C out. I just stood on the gas off the line in 2wd (not even a chirp from the BFG AT KO's )

I did a second run after driving for 20 minutes, 15.164 at 91.56mph

G-tech run rpm and tq vs rpm
G-tech speed
G-tech HP vs time
G-tech Gs

I still need a little more tuning done, the LTFT are +9-12%

Does 14.77 sound right?

You should have the HP and weight to run 95mph with your setup. Only problem is your times are varying soo much. I avg. 95-96MPH on my G-Timer which is only .5-1mph off track #s so I know I am withing the 94-95mph range and I have a lil extra weight on you I think. I am at 4700lbs right now.

What did your truck dyno at and what kind of dyno?

I think the reason why the thing is not consistent is the tune, some days it runs great and other days it doesn't seem to run as well. I think I am running rich at WOT 920-955 on the O2's, and because my LTFT are + it adds fuel based on the % its at before you go to WOT. The truck is a dog out of the hole too, till about 3000 rpm.

I have never had the truck dynoed.
