Ok before doing so I spent weeks looking through forums and calling different shops and decided I wanted a ECU flash for me Moore Mafia out of Taylor's S.C. was the most confident and knowledgeable on the 2023 GSXR-1000 or any year. But the difference was very impressive. Note I previously added a full M4 Gp exaust system and a K&N racing air filter but after the flash it felt about as much increase of going from a 600 to a thousand yet another time I was most impressed with the quick shift...
