finally a stock to stock race , you got a factory freak , congrats.

 

Our best guesses based on dyno errors (which is highly subjective) and timeslips put into ET calculators has them in the 325-335hp range at the flywheel, on average. The 5 speed auto helps too. It isn't until 4th gear that you hit a 1:1 ratio so the spacing of the gears is tighter for less of a drop off. They made no changes to the 05s. It is still only one engine and one transmission that you can get for all Titans. If they ever come out with a high output version I'll probably wind-up with one.

 

It would cost more in lost resale value selling your Chevy than, say, putting a blower on it!
