I have tuned my truck and shift points on its tranny but now I got a 2020 Indian Scout. I?m not going to do any major engine work except possibly an intake and it already had a short clamp on exhaust. I noticed I can but the adapter and 4 credits to tune it but what all can be changed? Can you just adjust for additional airflow with the intake and exhaust for 5 HP or are there additional benefits? Seems like it might be a decent investment for minor changes. Anyone have any insite?
