Can the S3 280 kit be installed without a programmable throttle body, will it self adjust to the bigger displacement? or is a programmable throttle body necessary. Thanks, Ken

You actually need the titanium header pipe also.

I have a 27mm mitani header pipe on it now. Ken

increasing the bore does not require re mapping but is advisable, otherwise there is no real benefit? It will only self adjust within the parimeters already set. My guess is a standard bike re-mapped would be as good if not better than an unmapped 280, at least my 4rt was.
