I was way over thinking things until i met Zach fuller from starlight diesel. sitting in his class i relized i was overthinking everything. now i get all of it. tuning for big injectors and pumps is not that hard. may take time to dial in but once you get it its fun. i like that i can drive a vehicle now and see the ways its reacts to my changes and make some changes to achieve the the desired outcome im shooting for.
