Well, after having my Hot Tune loaded for 2 days I have run over 1500 kms with it and all is have to say is WOW!
THIS is is the truck it was meant to be!! I have no idea how anyone who puts serious miles on their truck can live without this tune.
No more near-misses when hitting the go-pedal to get out of a tight situation or changing lanes in heavy traffic.

The tune changes your truck from feeling like a Prius to feel like a real diesel truck!

- Mileage continues to improve with every 50 kms or so
- idle is MUCH smoother
- 1.5 second pause before trucks reacts to accelerator is GONE!
- DEF use seems to have slowed
- acceleration is smooth and gears shift very nicely.
- the engine seems to run tighter and more efficiently.

If you are on the fence over flashing this tune you will have NO regrets doing it!

The only negative I have experienced so far is valve chatter when starting up a hill in 6th (1500 RPM) and it doesn't gear down soon enough since it thinks it is so much tougher now. No chatter noticable when further into the power band hitting hills (2000 RPM). Maybe this is something that will be fine tuned in a future update?

My 2 cents worth.
