Now it happens no where else on the track and i have tried to tune this out but havent had any success, it has been this way since new. I also have a much cheaper standard novarossi RX221PS and i have never had any sort of similar issue with this engine. Its a bit of a pain because im getting much better lap times out of an engine that costs almost half as much. I have never been all that impressed with the pace of my IDM compared to similar prices JP's.
