Into the @m*m^2

I had this all here earlier today, but felt that maybe it said too much. Now that I have some more time I decided to redo.

My Truck: 2014 Pete 388; 2013 ISX15 cm 2350; 485 HP; 1850 Torque; 3.36 rears; LowPro 255/70R/22.5 Drives and Trailer; 295/75R/22.5 steers. 46,500 empty weight. OD 581,694 at the time of change. I'm a car hauler, 3 on the truck, 6 on the trailer. My MPG was always horrible due to the nature of the beast, 5 was about normal and 5.2 was exceptional (down hill wind up my back side) and many times 4.8 was present.

I bought this truck in Nov 2017 and from then to date I've spent over $20k on that VERY FLAWED EGR/DOC/DPF/SCR MESS of a system. And as a result I had enough! So after a few inquiries and few phone calls the deed was done.

With the help of several people here, I did everything I was told to do down to the letter, missed no steps, took no short cuts. And the first thing I noticed was a very smooth idle. It never idled badly, but this was noticeably different.

I had my first load last weekend since the 3rd week of March. I was approximately 78k gross and a big SUV back on overhead, so plenty of wind drag. Dallas to Colorado Springs, 714 miles, 600' elevation to 6600'.

5.58 mpg actual, a full .5/mpg increase. The pedal response was amazing. It would go from 0 to 30 psi boost in a blink of an eye. Hills that I would previously have the pedal on the floor were now blowing past 32 psi with 1/2 a pedal. I'd immediately back off, down shift and feather the pedal up the hill without missing a beat at less than 30 psi. The hottest exhaust manifold temp I saw during the entire trip about 600 deg. Most of the time it would hang out at around 425 deg. Keep in mind nothing was done to change HP Torque etc. but the performance and response from the engine now is quite shocking, to me. I'm sure to others of you who have gone down this road know what I'm talking about. I honestly didn't know what to expect, but I can safely say I didn't expect what I got. I'm truly driving a brand new truck and thoroughly enjoying the learning curve.

I don't know what tomorrow will bring, but for today, I couldn't be more happy and to all of you who helped me through it, THANK YOU! You know who you are and I appreciate it more than you can know. I hope I can repay the favor some day.
