Well i would have to agree, those numbers are way on the high side, especially the torque, and his truck is a 4x4. Id say its a spike on the dyno graph, or was this a WOT run from a stand still with the trans shifting, as that will cause the numbers to be higher than they actually are.
performed an normal run in second gear no spike, graph is smooth as could be, i will get a pic of it cant guarntee the quality

Why in 2nd gear? If its an auto your supposed to dyno in 3rd to get an accurate reading. Is yours a stick?
auto i thought 2nd was 1-1, its sure seems like it when driving,
nope 3rd is 1:1
in 2nd you still have some torque multiplication through the gear ratio of the trans, that is probably why your torque is so crazy high but your HP is normal.
thats $H!@*y
Take it back to where you had it dynoed and ask if they will do one run for free since they were doing it wrong and that way you'll know exactly what your putting down.
With your mods it should be about 275ish HP and 285/295 tq
Maybe they'll go for it.
yeah and i think on the second run it might have downshifted to 1st, because it went from 344 TQ on the first run to 421 TA on the 2nd run.
I think the power numbers might actually be alittle on the high side as well, because the dyno actually only reads the torque output and gets the horspower reading from a mathamatical calculation, and with the TQ being way off i think it might be affecting the HP readings.
i c if i can, but it did not downshift started bout 30-32mph in 2nd and dumped it
