yeah, that skinny thingy on the far right side of the floorboard should be pushed down pretty hard. The farther down it goes the better results typically

Just kidding pard, have fun I wish I could get on the rollers.

don't let it hurt your feeling when you dyno was less than you think you should. i guess 295 rwhp

I say 280. those 37s may hurt you a bit. But I know nothing about PSD so don't judge my prediction.

i was told by the dyno opperator that tires didnt matter that i could 2 runs one with stock tires ond one with the 37s and still get the same numbers

That doesn't sound right to me, I could be wrong but won't it take more power to turn a bigger,heavier tire?
I know my truck feels totally different when running 35's

i not sure

There is a lot more rolling mass, I bet it will be lower, but not a huge amount. The best thing about the first time is you know where you stand for the future. My first run sucked

, so I upgraded

The dyno operator is a fool, a taller tire has more mass, the dyno measures how fast you can accelerate a known mass for it's readings. Anytime you add weight to the driveline you loose dyno HP. My truck with 34' tall, 150lb apiece Ricksons will dyno 7-10HP lower than the same truck with stock tires. It just takes power to spin large tires, and that power is not shown on the dyno reading.

i think they can kinda figure out the number that the truck puts out

It will read, it just will be a lower reading.
