Hi all. My beast is 2014 with Australian Foran pipes and catalytic converter removed. 20000 service done a few thousand Ks ago. She's always had a flat spot/hesitation when opening throttle at low revs. I installed a Booster Plug and all it seems to do is slightly reduce the loud backfire on deceleration (still has flat spot when connected). I'm thinking of ordering a Dynojet Power Commander V. Any advice would be appreciated.
