2015 Colorado shifting issues

Hi, I have a 2015 Chevy Colorado and I'm using the latest update on an my inTune. I've recently lifted the truck and now run 33"x 12.5" tires. The Diablo Tune helped a bunch with pulling the bigger tires around and recalibrating the speedo. The only issue I have now is getting the truck to shift into 6th rear at highway/interstate speed. At any point over 60mph, I pretty much have to be going down hill to get into 6th gear. What if any parameters can I adjust to help with this problem?

have you verified the speedo calibration?

Yes, I've checked it with a GPS. It's dead on accurate.

Is there a tune for the 4cyl 2.5 L ?
Love the truck but the shift points are just terrible
Thanks!
