It is disappointing how little progress has been made on the tuning side of things, especially since these trucks have been out for a while. S*partan has been hinting at "big things coming" via Facebook, but it looks like all they were talking about is OST functions for 11-16 trucks. While that is quite an accomplishment, it's a shame that 17 tuning doesn't even appear to be on the near horizon. Also, I can't say I'd spend any money with them because they seem to disappear whenever there's a driveability issue or CEL that can't be fixed quickly and easily. Not looking to start anything, but I think there are still people on here with their tunes and CEL's due to high flow intakes.
Getting back on track, my 17 runs strong enough that I'm not even interested in an all out race tune. Something mild with better transmission shifting would be great, and if the truck picks up some mileage from certain components "falling off", that's even better.
