10K UPDATE:

Truck is doing awesome! Averaging around 20mpg still with my 35’s. Speedometer is around 3 mph off at 60mph so once I get out of my cheesy third party warranty, I’ll recalibrate speedometer and fully delete.
I only have egr blanked off and unplugged, I have noticed the truck hardly used coolant before but it’s staying in a steady spot since I topped it off when I tuned and did the last oil change.
Speaking of oil, I’m around 7k on this oil and it’s still able to see through it just a smidge unlike before when 100 miles made it blacker than asphalt.
I have no issues pulling my 19’ ranger boat, nor does it even notice my 7x12 enclosed v nose trailer loaded with equippment, tools and supplies.
I DO wish the trans tune was a little more responsive with the pedal. Sometimes I feel it should shift a little sooner when I’m going 10-20mph and punch it, but that could be because I haven’t changed my filter and fluid in the trans yet
I have 143k on it now, bought it with 113k. Tuned at 133k. I have changed (see glow plug story on another thread) one glow plug, the backup camera because it was blurry, wheel hubs, front and rear pads and rotors shortly after purchase, regular oil changes from 7-8k miles, along with fuel filter changes at the same time. I’ve replaced 3rd brake light when I bought it due to cab leak. Changed out reverse bulbs, cargo bulbs, cabin map lights, headlights and fog lights all to led. Added window vent visors, window tint, 1.5” wheel spacers all around, 1000hd bags to the rear, 1.5” body liftand 2” leveling kit to the truck.
I love my rig, she serves its purpose!
