I purchased my 2016 Ecodiesel used, back in May. I had the AEM settlement tune done at the beginning of August. Truck absolutely sucks now. In the morning, it's the worst. No power until the truck is fully warmed up. Major peddle delay. Warmed up/hot day, it's okay, however the fuel economy dipped a lot. I'm now in the 13's on average. (To be fair, I also lift my truck 6 inches recently and went from the 33's to 35x12.5x15 BFG AT KO2's). I'm also doing much more city driving than I was, so that doesn't help either.
I had delayed ordering the GDE/PPEI/SFT tune as I was waiting for my AEM settlement check to come before ordering. It also sucks as I've had my H&S compound turbo kit sitting in my garage for a couple of months now. Now that I needed the tune, I was saddened to see GDE/PPEI no longer offered it, because of the EPA/CARB issues.
Thankfully, SFT (Sofa King Tuned) is still around. They are our last hope (that I know of). I purchased their tune/unit on 9/25/19 and received the OBD2 programmer yesterday 10/3/19. Switched out my ECU, connected the device to my laptop. Downloaded the stock ECU file and submitted my ECU file to the SFT tuning server today. Hope to have it back within 24 hrs (as they ask for 24hrs to receive the file).
For those wondering, I'm just doing the Stage 1 tune (while truck is stock). I'll do the Stage 2 tune later, after I delete everything and add the compound turbo kit.
I'll post back, once I've received the tune ECU file and have applied it.
Here's a pic of the truck with my lift installed, a pic of the SFT tuner, and new ECU.
- Lift is a 6" Superlift kit (installed painstakingly by me, my awesome neighbor, and my dad, over the course of 5 days)
- 1.5 inch, hub-centric spacers used to retain the factory 20" wheels
- New ECU purchased from a dealer
