scalars injectors

    Does increased scalars mean tired injectors?

    I’m currently running stock fueling system with Stage 2 LPFP for occasional E50 use. On 93 oct for the last few years I’ve had to increase my 3D scalars in my custom 93 octane tune just to keep STFTs in check. Is needing to increase scalars a telltale sign that the injectors are getting tired?
