I would expect very little mtce. after the initial tune in the car is completed. I have a Blown and Inject Vette running the same type of setup and the only mtce I have done to it in the last 3 years is to change
oil and spark plugs. These systems adapt to conditions, wear on the engine, etc. pretty well and there is nothing that will wear out in the life of a "hobby car" like this.
