Apologies if this has been covered elsewhere but I have removed the cat from my Sp and used a Black Widow link pipe O2 sensors are still in place, AIS valve is gone as is Exup , there seems to be a lack of bottom end torque and power now and it feels like a flat spot , I am having the ECU flashed Using Woolich software as I write but am unsure if all modes will change with the one map change or if they have to be done individually , I am in NZ so tuners are a bit limited ecu is at Triplezee cycles

Hi just had mine done with the woolich tune,yes all modes are tuned together and i think they omit the o2 sensor anyway. most tuners have access to different variations of exhaust ect so you should be ok . much nicer bike to ride when its done right. enjoy.
