ALWAYS fine tune your motor when it is hot, after running a tank through at least. It takes time for the chassis to fully saturate and act as an efficient heat sink. If the crankcase temperatures are not in the normal operating range, the fuel will not be vapourising as efficienty. If race tuned under these conditions, once the the crankcase is hotter, the fuel will vapourise much more efficiently totally changing the tune. Get a basline tune on the box to get the motor running certainly, but don't tune for racing or normal running until you have the motor up to temperature and the chassis saturated.
And throw that temp gauge away too Nick
