I have 2 Brother carbon SBK exhaust+K&N filter+ +Gianelli catless test pipe. Will a stock power commander or juice box pro work or do I need to get it dyno tuned? Any thoughts?
I have a laser xtreme exhaust, airbox mod and k&n filter. It was running way to lean.
Only a Pc won't work or it must auto tune very well.
With a pc + dyno you will get the right air/fuel ratio on all throttle positions an trough the entire rpm range.
My bike is a lot smoother. It has less power dips in the rpm range. And it accelerates a bit faster.
Top end HP gain was not that great 1-2 HP but where the dips are it was 5-6.
I would not install a pc without a dyno. I have seen the fuel map it was ranging from +4 to -4 setting a single value won't cut it. It differs with different throttle and rpm.
