WHAT TUNING CHANGES WILL BE NECESSARY?
The changes necessary will vary from engine to engine and depend on how many parts are coated. In general coating the combustion chamber surfaces will allow you to run less initial timing with no loss of power (usually a gain will occur). You may also be able to run significantly less fuel, due to the more efficient oxidation that occurs with the coated parts. You should be able to run smaller jet sizes. Obviously no specific recommendations can be made as every engine/combination will be different.
