Diablo is Baaad!
Order chip a couple days ago, UPS showed this morning with it. Yahoo!
It took 1 1/2 hours to instal, un-install and re-install. We they say make sure the contacts are clean, they mean it. Power gain is about same as when i installed injectors, cam and headers on 351Wb ut a whole lot cheaper.
Thanks Ken and the folks at Motorhaven.

The truck I but the chip in, is a 2004 F250 SD, V10, auto, 3.73:1, & low restrict. muffler on stock pipe. I hope I didn't lead you to think I was chipping the 1989 F250, which has a 351W Jasper engine (I believe its a Stage I or Stage III, whichever is their next step up from stock) with performance/tow cam, larger injectors, muti angle valves, shorty headers hooked to a rock crusher 5spd & 4.10:1. I had the engine built and installed at a local shop, cause I stopped doing any mech.work when they stopped using points and carbs. Good luck.

supercoop,
I agree that the Predator is awesome, but I am an engineer of sorts...well I am a computer systems engineer...anyway I scheduled some time on the dyno today and here are the results I netted:
Testing was done on a 1500 HP Mustang Dyno, 94% relative humidity, 80 Degrees Farenheit, Barometer 30.01 steady
Truck: 2002 F250 SD 7.3L PSD CC 4X4 SB
Mods: Open Element K&N with CAI (homemade), Wastegate Unplugged, Adj. BPRV
Boost: Constant 24 to 25.5 PSI
All numbers are rearwheel
Tune Hp TQ
Stock 208 415
Tow 241 454
60 HP 268 553
85 HP 290 575
100 HP 300 593
All in all well worth the money. Now waiting for Wicked Wheel to come in some that I can get rid of the annoying compressor surge.

yes you make on avg with auto 20% less maybe 25% with 4wd
on that dyno it is loaded so numbers will be a little bit lower
my 03 5.4 is rated 260hp and 365 tq at crank
on mustang dyno with diablo chip, mac air in take and maganflow catback - i got
220rwhp and 300 ft lbs torque
now the hp number is lower than what it should be because that was at 4300 rpms - peak power would have been around 5000-5100 rpms
truck is also a 4x4
diablo chip was worth 32 rwhp

I think if you take into account for the 20 to 25 percent parasitic drivetrain loss, the numbers for stock will be very close.
My intent was to show that the Predator programmer was actually producing the numbers as advertised.

Well your mission was accomplished, but I didn't mean to high jack this thread and turn it around like this. Sorry!

No harm....As a matter of fact if you use the 25 percent as a factor then that means my truck with simple mods in stock form with no Predator software load is making in the neighborhood of 265 HP and 550 TQ at the flywheel... not bad with just an open element filter.
