Provides up to 100 HP increase on older ones and now the new 140 hp claim. Evolution or Race Evolution. Which one is it? The price looks good if it's the racing version. It may not be hard to resale it and get your money back. Not so good if it's the older one.
Depending on how you drive the truck it could require DPF replacement or cleaning sooner than normal. You might also see EGR clogging. You could expect the same result from most any tuner because it will depend on how you use it. Some tuners may improve your results but it's going to depend on your usage of it. The truck has to run very clean to prevent problems.
Engine and transmission tuning is different on different tuners so performance results will vary quite a bit.
