Middleton(?) did track times before and after the Ford Performance tune, the 2.3 performance the same to worse on regular octane.Hi @LethalPerformance
I have a question regarding the tune and the requirement to run 91-93 octane to achieve the HP and torque gains. I understand the need to run the premium fuel to observe those gains but what happens if you run 87? Will the engine management control simply regress the timing and other parameters it changes like a stock engine and maintain the stock HP when you are using 87 gas? (which would be good if this is how works)Or, will this engine run the risk of pre-ignition/detonation with this tune on 87 gas? Thanks in advance.
