obviously if morgan is willing to turn down money when he owns a 60 thousand dollar dyno that he bought specifically to tune cars he must be doing it for a good reason. He has used it before and was not happy with the results on certain setups. unlike some businesses he actually cares about the quality of product that leaves the shop and customer satisfaction, and not just getting a quick buck.
the problem is that you have an uncontrollable variable in the tune, the stock ECU. think of the stock ECU as a base and the emanage map is built on stop of that, so when the ECU starts adapting to the turbo setup your whole map changes. a honda ECU has no mapping at all for positive pressure so when you run a turbo setup you have to put a check valve before the map sensor. so when you are at 10psi the stock ECU thinks you are at WOT N/A and if it doesnt see AFR values that coincide with that it will try to make it happen.
