Right now I have a tbr slip on and a juice box pro running the tbr map. The bike runs better but it still has the flat spot. I also have the ais block offs and read on this forum that this combo might lead to eventually melting the cats. My question is if I end up purchasing the arrow headers what map should i use with the arrows and tbr slip on? Would the standard tbr map supplied with the juice box be enough? I also have considered the graves full exhaust if the above combo wouldnt work but I didnt want to have to pony up the cash for a pcv on top exhaust. Any advice the people on this forum have for me would be appreciated. Thanks in advance.
