Daimler-Chrysler should offer to buy back the vehicles from people who are tired of the recalls, lose of power and offer additional warranties to those who make the choice to live with L.O.S.T. power and lower resale value of these vehicles.
I am still on the fence on whether to get my 2005 to the Dyno I think me and Weegie5
Would have a race. Mine defiantly is less powerful than when new.
He posted a link to his results and they show less than 125 lb-ft of torque at 2,750 rpm rising to a peak of 193.1 at 3,550 rpm. Horsepower peaked at 134.3 at 3,750 rpm. His chart starts at 2,750 rpm.
It would be unmistakable to have 295 lb.-ft. of torque at 1,800 rpm then fall to 125 lb.-ft. at 2,750 then rise to 193.1 at 3,550 rpm.

New Customer Satisfaction Recall – F37 page 30
Buy back for me; count me in on the class action if the dealer refuses.
The 295 foot pounds at 1800rpm is engine torque at the flywheel-- not at the rear wheels. You never have as much at the rear wheels in any auto-- especially one with an automatic tranny. So no dyno would ever show 295 pounds of torque at the rear wheels with this thing stock. The torque peak is indeed accurate- the torque converter does what it states it does-- it can allow the transmission to turn at a different speed than the flywheel-- which is why you have higher numbers for the peak torque at the rear wheels. "4-wheel drive and SUV" mag dynoed this thing and then chipped it and dynoed it-- I can't find my copy of the magazine though. The numbers they had before chipping were not far off from the before dyno numbers posted in the other thread.
What the "before F37" and "after F37" dyno results posted in the other thread did show, however, is a loss of around 10 hp and 10 foot pounds of torque. Working those numbers gives you about a 5.334% loss of torque and 6.40357% loss in horsepower. Kinda crappy, I am not happy with that. I am more concerned with the low RPM torque being hampered by the higher stall as I bought this for off-road use.
I wonder how much of this torque reduction has to do with the torque converter and how much with the reflash? I can fix the torque converter-- the TCM is another story. If they have messed with the HP and torque by having the TCM retard power then I am not sure what we can do to get it back short of reflashing the TCM and flushing our warranty down the drain.
