JUST DYNOED H&S 300 TUNE

[08BIGRIG]

I just got back from the Dyno Days at Beyond Redline in Green Bay, WI. I had the H&S 300 tune loaded up and got 587 hp and 1188 ft/lbs. I was pretty happy with the numbers. Also want to say thanks again to the guys at Beyond Redline for all they did today for everyone.

Got this off his sig on PowerstrokeNation:
2008 F250 Lariet 4x4 4"Flo-Pro Downpipe, 4"Downpipe back AFE Exhaust, H&S Black with 300 tune, Dirty Diesel Cold Side Pipe, Afe Stage II Intake, Air Dogg 165 Fuel Pump.

wonder how much that Air Dogg helped ?

[08BIGRIG]

I would say that the Airdog helped a little with the 300 tune just because I know that with the stock low pressure pump, there was fuel cut at wide open thottle with the bigger tunes. The stock low pressure pump on our trucks is pumping at 6 PSI and with the bigger tunes, it drops down to like 3 PSI at wide open throttle and cant keep up. That is the reason that I went with the Airdog pump. She rolls the coal when you stand on her a lot more with the Airdog than it did without it.

Looks like the 300 is spot on if you look at stock numbers of 280-290 hp... but the TQ looks a bit low?

Looks consistent with most other tuned 6.4's with a 280-320 HP tune. My truck did 595/1220 with the Spartan 310, so there isn't a huge difference in torque output. Also remember that every dyno is different. I have seen some dyno sheets read 1300-1400 ft lbs/tq on these trucks with similar horsepower numbers as mine and the OP's.
