Do you have access to 93 octane fuel? The first tune will always be the softest tune and its crucial to datalog and monitor AFR readings in order to get the most benefits and optimum feel in performance and it will take roughly 5 tune revisions and some have had roughly 10-20 tune revisions before they were satisfied with the level of performance and so may variables to consider such as mileage staying on top of maintenance aspect so due update your signature with your current vehicle and a list of all your mods,thanks.

I can see maybe 5 revisions. If I need 10-20 I think I might try another tuner. I have had several mustangs never needed 10 revisions. Maybe ecoboost tuning is different?
Was that with changing mods as well? I currently am on Rev11 of my tune, but started tuning for an E20 blend at Rev6, so I have 5 revisions on the pump gas tune, and am on the 6th on E20 tuning, but we are making one change at a time, first set of Revisions was to dial in boost, now we are dialing in the Spark Advance.
I am unsure how others do it, but I am also sure there may be need for a few extra revisions when a new mod is added, for instance when I add downpipes, I will need a new rev to my pump gas tune and E20 tune. Depending on the cars behavior there may be need for a second revision or even third at that point.
Weather changes also may necessitate tune changes, due to winter blend gas, etc. Though once a tune is dialed in it should need minimal revision. I think the biggest thing is how the tuner does changed. AJP does very gradual changes, and only works on one major parameter at a time, so that we can know for a fact how the change is affecting things. I like this way much more than a tuner who throws boost, and spark, and other changes at you all at the same time.
