Correct. Comp has to use the same specific Sunoco fuel as Pro Stock, SR-18, which is very inconsistent in its formulation. It requires a complete different tune, the fuel batch varies the performance of the engine and does not always pass fuel check even when it is fresh. Pro Stock has experienced the same issues as Comp.
