'01 7.3 underspec'd hp and torque?
Were 7.3 PSDs underspec'd or is mine some sort of superstar? at the crank ratings were 250hp and 505 ft-lbs for factory automatics. Yesterday I had mine dyno'd at PHP and my at the wheel numbers were 242hp and 504ft-lbs. I would have expected a drivetrain loss of 15-20% with results more like 215/430.
Performance mods to my engine are AIS intake with Zoodad and 4" MBRP exhaust with muffler. The only work to my truck other than regular maintenance is the Ford HD4R100 transmission, passenger side UVCH and the IDM (new Ford unit). I'm the original owner and it's never been tuned... Factory PMT3 tune on the ECM. My truck has 195000 miles on it.
Here's my dyno print out
