First things first. Huge thanks to Ray @Double R Diesel for working with me on this. Ill post another thread for that.
Truck (and relevant mods):
2014 Mega Cab 3500
19.5 Vision wheels w/ Hankook DH01 245/70R19.5
NAPC Heavy Hauler Full Race Transmission
RaceMe Ultra
S&B Intake
Fass Titanium 150gph
5" TBE
Grid Heater Delete
Pusher Intake Horn
Stock tune for deletes only:
304 HP / 634 Torque
RaceMe Ultra +200HP tune with max timing and rail pressure
495 HP / 976 Torque
Double R Diesel Tune
466 HP / 946 Torque
Did three days on the dyno, a ton of log files sent to Ray, and tested a whole bunch of different setups and tunes to get it dialed in. Rays tune made slightly less power but when you look at the graph you will see a huge flat spot in the RaceMe tune just before it peaks. So while it made more peak power the curve getting there was significantly less. Ray was able to get more power all through the RPM range where you actually use it versus just a peak HP number. Ray can chime in here too as well but from my understanding the peak power couldn't be made without draining the fuel rail under his power curve. RaceMe was able to hold the pressure with a less aggressive acceleration curve to hit the peak power. The usable power and fun to drive factor is much better on Ray's tune.
Very pleased with the results and will be back for more once I get a turbo and injector combo figured out and installed.
Graph 1 shows stock, RaceMe Ultra, and initial tune by Ray.
Graph 2 is the final set of runs on the finished tune.
