550hp powerstroke?
went to edgewater friday night and saw a 2000 350 2wd dually run a 15.10 in the quarter. had to talk to the guy and he said I was free to "snoop" but he didn't really give any secrets away. he did show his dyno sheet that was showing 497hp and 983 lbs of TQ......a programmer was laying in the floor, he had a 4" exhaust, and an airbox of some sort. NO PROPANE. my question is what does it take to make a super-duty that quick? pretty sure a few other things had to be upgraded to take that kind of power, mainly the tranny, but really couldn't see that much difference from my truck.

550hp powerstroke?
hey, u can get a performance tranny, automatic that is, that will only take about 5% of ur power away rather than 15 or so, i did that to my cummins and it ran awesome, but i switched over to the PSD and i will NEVER go back. the cummins is great, excellent reliability and u can just run it into the ground but i can out tow, out accelerate and out just about everything with the PSD compared to the cummins and i havent put the new tranny in yet.

To get that much power out of a PSD, you'd need to do some pretty radical modifications. Primarily, the biggest issue is the fuel delivery system. It's relatively easy to alter the fuel system on a Cummins, and generate some huge power numbers. On a Powerstroke, however, your options are more limited, and getting to that level involves an investment of cubic dollars. You can change out the injectors, and you have options there as to which to use. Some flow a lot more fuel than the stock ones, but you hit a point where you've gone as far as you can. You can get some pretty significant gains through intake, chips, exhaust, etc., and get it to the ground better through better trannies. Beyond that, it comes down to fuel delivery.
