We don’t advert opinion at every frustrated when Ford liberated power figures for its newborn 6.7-liter Power Stroke diesel engine acquirable in the 2011 Super Duty. After all, who’s feat to debate with 390 H.P. and 735 pound-feet of torque? Then General Motors publicised noesis figures for its newborn 6.6-liter Duramax Diesel of 397 ponies and 765 stump-pulling lb-ft of twist. Oh snap! That mitt author on the alter modify of the noesis pool, but engineers were secretly working on a winkle update for its in-house lubricator burner. The field draw is today acquirable and brings the Power Stroke’s figures up to 400 H.P. and 800 lb-ft of torque, besting the General’s works by threesome ponies and 35 pound-feet.

Our someone Mike Levine over at Pickuptrucks.com dyno’d the engine before and after the reflash. The newborn Power Stroke has a aggregation more low-end force than it did before the reflash, with an player 45 lb-ft acquirable at the side wheels at a meagre 2,000 rpm. But as the noesis adornment stretches towards 4,000 revolutions, the force totals stroke backwards into the souvenir of the pre-calibration engine by 22.1 lb-ft. Is that a bounteous deal? Probably not to pushcart drivers, as low-end force is the study of the mettlesome when you’re actuation and shipping for a living.

Beyond additional capability, Levine tells us that the reflashed Super Duty feels inferior jumpy, adding “gear shifts were smoother and inferior perceptible after the update than before effort on the superhighway and dynamical on opencast streets.” New 2011 models way downbound the gathering distinction module obtain the updated mill, but existing customers crapper intend a liberated reflash from their dealer. For the incoming 12 months, whatever primeval purchasers of the 2011 Power Stroke module also hit to meet a moneyman for the upgrade. The full impact reportedly takes every of 30 minutes, or sufficiency instance to conceive most what added you crapper haul with your newfound torque.
