confusing 160/100 dyno numbers

I was at a fall brawl dyno event in PA this weekend and decided to dyno the truck and I got what I thought was A little confusing numbers. I am running DP tunes on my set up (mods in sig) 120r - 418hp 815tq, 140 all out pmr Drag tune 418hp 839tq. Now I have ran my truck at a local drag strip a few times and my best time on 33x12.50s was 13.8 and Ive ran 13.4 on 265/75r16s. With my truck being ext cab long bed 4x4 wouldn't those 1/4 times suggest something closer to 450whp mark? I will have to dig up the time slips for exact 60ft and mph.

I don't know all the math, but I do know that you'll need to know how much your truck weighed during your runs, as well as how "heavy" the dyno guy made it.

I have had my truck on the scale at work and it weighed in around 7100lbs and change if I remember correctly the night I raced on 265s. I did the 1/4 time calculator about 4 months ago and it came out to 450ish whp from trap speed 480ish by time1/4 time which part of the reason I was confused when I dynoed.
