Roo system chip

Dose any one have a roo system chip I think my chip is putting too much fuel in even on the lowest setting
Do they fail

Is it smoking? Why do you think its overfueling?
If the way the car drives has suddenly changed maybe disconnect it and take it back to get it checked. You don't want tow on the highway with a chip that is overfueling the engine, could become expensive.

What are your egt's. They should be high if overfueling.
