This is the minimum I would expect. and the power and torque will come sooner.
The truck will feel a lot more torquey and powerfull. You won't need the dyno to tell you that.
First test ride is going to be a eye opener.
Make sure you have correct valve springs
the fuel system has to keep up @ WOT.
carb is a bit too small.
You have barely scratched the power potential.
further: the dyno only tells you how much power is created.
it does not tell you if you are making good use of it. (acceleration)
