Interesting idea.  I chipped my diesel and gained a little horsepower, quite a bit of torque, and the fuel consumption decreased.  It was a noticeable and measurable improvement. We really like it and haven't seen a problem in the 5 years and 50K miles since we had it done, except blown transmissions (2, 4R100) due to the increased torque and my heavy foot with big loads. (triple axle trailer and commercial fishing boat).

Unfortunately, most gas engine tuners yield a modest increase in horsepower, frequently at higher revs (this tuner does show an increase at lower revs) and also increase fuel consumption.  The results of the test article showed an average 3.7% fuel mileage decrease in the class A motorhome.  Considering the modest increase in horsepower curves, I'll stay stock.

If we had diesels, it would be a different story.

I installed a 5 star tuner on my V-10 powered Chinook Glacier, ran it for a summer then took it off. While the tuner did improve power slightly, as mentioned above it did it at higher RPM's and my fuel mileage dropped slightly. Shift points were held longer (again higher RPM's) but less downshifts on slight inclines was a plus.

After installing the tuner, at times I would notice a slight ping from the engine, the use of premium fuel helped put the tuner was supposed to work with 87 fuel.  Went back to factory tuning and will stick with that...

It sounded good on paper so I appreciate the real life experience you all provided.  I'll stick with stock.  Happy New Year!
