Anyone worked with 5 Star Tuning for a diesel tune?

Looking for some honest opinions on 5 Star Tuning for diesel trucks. I’ve got a 6.7 Powerstroke and I’m considering one of their tow tunes. Not trying to roll coal, just want better driveability when I’ve got the trailer hooked up. Anyone have experience with their diesel calibrations?

I run their 50HP tow tune on my 6.7 and it’s perfect for what you’re describing. EGTs stay in check even pulling a 10k lb fifth wheel through the mountains. Shifts are firm but not harsh. Big improvement over stock.

I’ve had their tunes on two trucks now — a gas F-150 and a Super Duty diesel. Both were huge upgrades. For the diesel especially, the throttle mapping is way more predictable. No more dead pedal feel.
