Our programs are undetectable by dealership diagnostic tools, so basically they won't know the ECU has been upgraded with a better program. The gains are noticeable, but normal driving in and out of the service bays, they will not tell the difference. And the program will not affect other parts of the car as the increase is not alot and will not put alot more stress on other parts of the car.

Upsolute programs basically optimizes the use of 91octane fuel, so basically there is no harm done unless you are running the program with fuel lower than 91 octane. I have had several customers letting me know they got an improved 10% fuel mileage, so basically they got roughly 50km more per tank of gas together with power increase and smoother throttle response.
