I'm currently looking at both of these. The 50 would be fine for what I'm doing but I need at least 45 PTO horsepower for a hydraulic power pack. There is about a $7000 difference between the two and from all I can tell it's just tuning. Many moons ago when the power stroke diesel first came out I burned hundreds of power chips and set up programmers that I sold through my business. It appears tractors have caught up to this technology now as I found the chip for the tractor to take it from 49 hp to 60 hp. Anybody messed with these? Sure easier to take than a $7000 up charge for 11 hp. Looks very similar to the tuners I sold for Powerstrokes.
