Missing 7.3
Hope someone can shed some light on my dilema,I just traded my 2002 f350 cc drw sb 7.3 4.10 gears 4wd with 60 hp chip , for exactly the same truck for 2005.I pull a 14000# fith wheel And was hoping the stock 2005 would pull as good as the chiped 2002 , But so far have been very disapointed, the 2005 has no topend power . Am I missing something Or is this just the way it is.I have 2000 miles on new truck. I am sure missing the old 7.3 thanks for any wisdom

The 2005 seems stronger from 0 to 60 ,then falls on face over that.It will not gain speed in overdrive on the slightest hill ,and seems to shift down twice on big hills while losing speed

Mine is much stronger that previous 7.3. On the top end too. Maybe it needs to see the service dept.

i think you are missing the extra torgue provided by the chip. the 6.0 is strong but it cannot compete with a 7.3 plus a couple hundred ft.lbs. an aftermarket tuner will probably fill your void and then some. but you must admit, the handling and turning radius are simply fantastic on the 2005. add a little more torque and i think you'll be a very happy camper.
good luck

Oh, and when you say overdrive, do you mean tow/haul?

Yes there some nice changes on the 2005 the brake control is awsome and the transmission is very smooth , Just wish it would stay in overdrive and pull hard. The chip only added 100 foot lbs and 60 hp making the two trucks very similar . Chipped 2002 310 hp 620 footlbs, 2005 325hp 570 ftlbs

I think you might have a slightly sic one, now no worry it could be something very simple...I have towed next to 7.3 and the 6.0 just leaves them above 35mph...I pull a big trailer...see gallery...
