Let the fun begin...
Check out the numbers a TUNED '08 laid down. This is in the SuperDuty forum:

Just tuning -- no other mods, and on oversized tires.

From the first post in the thread:
" The easy part was for Jerry to tune the truck, the hard part was getting a 18' extended cab F350 with over size wheels, on my 16' dyno."
AFAIK, the stock 08s are putting out around 290HP stock. One was dyno'ed when I ran last weekend at 305HP, and that was after exhaust mods.

Here's the stock *FLYWHEEL* numbers. Subtract 15-20% for driveline losses and you're at roughly 290 RWHP that I quoted: "The 6.4-liter Power Stroke ® Diesel delivers 350 horsepower at 3,000 rpm and 650 lb.-ft. of torque...".
That's also inline with the numbers I saw when it dyno'ed last week, again after nothing but exhaust mods (305/649).

Yeah I had seen where he said he had it tuned then went down and he said it was stock.
Matt from Spartan Diesel is pushing close to the 500 mark with a stock truck with his tune and the DPF removed.

I look forward to seeing how these hold up at the 500HP+ level. It's funny on the timing too. I just commented last week that I was looking forward to seeing what the 08s would do with more mods & tuning. I guess I got my answer. Look out D-max & CTD!!

Wow that is some impressive numbers, now we know what a CR PSD can do. Just imagine with the emissions stuff taken off and some bigger injectors. Though I wonder if these trucks will be like the 6.leakers with tuners, just a little tune and you blow a head gasket.

Yeah, that's what I'm thinking as well. We'll see. From what I understand, the 6.4 is just a 6.0 with slightly bigger jugs, compounds, and extra emissions crap. Time will tell.

I though they completely reworked the 6.4s into a totally different beast. I wonder though what the new LMMs and 6.7s are putting down. I know Dodge is having alot of trouble out of these new motors apparently emissions and Cummins don't mix.
