Got another 6.7 together this week. Setup is a MPD single turbo kit, Engineered Diesel Billet 66/74, H&S dual fuler kit, FASS lift pump w/ TSD sump feeding the CP3, Stock fuel delivery feeding the cp4, and TSD customer tuning. Stock motor, stock transmission.
Truck started at 618 rwhp on the canned H&S calibration 4 with a logged 1850us pulsewidth. started adding some pw to it and got to 665 at 2300us. The last 100us or so was very diminished returns so in my opinion the timing will need to be increased further, or were starting to get into the territory of needing a bigger injector nozzle. Being as this was the customers daily driver, he chose to call it quits at 665. I personally think we could hit 700 fuel only on the same setup, but itll have to be pushed a bit. The drivability is great. the 66 lags a bit more than the 63/68 but as you can see on the chart, its a very broad powerband. Cruising 75 mph on 35 inch mud terrains the truck would have around 7-8 psi and run abot 800 degrees. it would definately be ok for towing and the smoke output is very minimal unless you smash the skinny pedal with no boost built.
