Does the 2004.5 reflash boost HP rating to 610, just like the 2005's?

After mine was done seems like truck has more power.

 

I was told it does and have no reason to doubt it, as far as hp..... if the math is there 325/ 6oo then figur about 330/610, this is just using cheat math too lazy to go through the real formula.... could be off by 2 hp diff? not much. all depends where this extra 10 ft lbs falls, what rpm.

 

The curves I've seen, I forget where, show the 600/610 torque peak being at lower RPM's and the HP peak is near it's redline where the torqe output is lower.

So the extra 10lb/ft might not equal any extra peak hp.
