I have been running my truck for the past year trying to sort it out. Took it to our local 1/8th mile track to work on the short times.

Truck is 3,300 with me in it, boost controller, ladder bars, Afco dbl adjustable on back re-valved by Mencer Motorsports for radials and single adj QA1 on front. Fronts are 3 clicks from full loose and Backs are full loose on extension and about middle on bump. Tires are 315/60/15 ET Pro with 17 lbs air.

Prior, I have gone a 1.42 leaving at 3,200 rpm on 4.5 lbs of boost and ran out to 9.91 at 135 on 14lbs of boost. I believe the truck should 1.29 when all said and done. Well, testing didn't get me close and I got worse. The track prep seemed to be pretty good, weather was a little hotter than I thought it would be, but wouldn't affect 60fts much. I tried to leave at 4,200 rpm (first vid) and then lowered it to 3,800 rpm (second vid), leaving the boost controller where it was.

I have an idea of what I think the issue/resolution is, but I would like to hear the experts (as I am know where near that).

First Vid I spun pretty bad and only went a 1.8x 60ft: https://youtu.be/gLF5ay9dIcs
Second Vid I lowered to 3,200 rpms and still spun and went a 1.56 60ft: https://youtu.be/COn8PqhZ2AY
