I know there are some who say you don't need a tuner; my Dyno tuner disagrees strongly. The ECU can adapt somewhat on its own over some of the rev range (generally part throttle and low to medium RPMs) but when in open-loop operation the ECU cannot adapt to the larger displacement, so it ends up running quite lean at full throttle and high RPM. Those who say that they got a boost from the big-bore kit in the mid-range but nothing on the top end, would seem to be confirming exactly that.

If doing a 300cc kit, I would highly recommend getting it tuned or at least using the wideband autotuning kit available for the PC V.
Links please! No one ever posted links and plenty ask!
There is a Delphi MT-05.02 or something ECU and looks the same but maybe wont tune?? again no one ever posted links or results.
