The 5.9 was also a 5 speed when Dyno by the ATI sub-contractor.
I wonder I can get a copy of Jeff's Dyno ticket. Jeff! Do you have your
Dyno ticket
And was there any mods made at the time of the Dyno run?
19.5 percent HP - rear wheel loss for Jeff's 4.7 Auto.
12.4 percent HP - rear wheel loss for Matt's 4.7 5 Speed without the K&N
(figure only a 7.5 HP gain)

Subject: DML: RE: RE: RE: Re: Jeff-Steven Question SC'd 4.7
Steven, my truck is a 5spd, so there is a different driveline loss with the
5spd than with the auto.
5spd is less. If we look at Jeff's numbers because he has an auto truck
we'll see that his truck dyno'd 184 rwhp/252 rwtq. My 5spd truck dyno'd 208
rwhp/285 rwtq (with airhat/airbox removed and K&N installed). Not an even
comparison, but obviously the K&N filter would not make a 24 hp Rear Wheel
difference, maybe 5rwhp, Maybe! So there is some extra driveline loss with
his auto trans. I'm gonna guess the 5spd is about 13 to 15% loss and the
auto trans. is about 20 to 22% loss. My 4.7L is rated from the factory with
230 FWHP not the 235 because my truck is the LEV version. I'm assuming
Jeff's truck is the non LEV version rated at 235 FWHP???
