Gearhead Tune and Impressions

filled the tank with a little bit of regular, no ACES, and the OAR has plummeted to -0.0607 after just a few miles.  I doubt its finished its path toward positive 1.  While this doesnt rule out anything like bad knock sensors, it strongly points toward the fuel.

Do other Tunes/Tuners have this problem ?
Just to be clear, right now the operating theory is that I'm dealing with crappy winter fuel.

If that is the case, then yes other tuners would have the same problem. However, Gearhead's tune auto adjusts. Right now, it's decreasing power back down to stock levels. Better gas will increase power.

Oh yeah I get that but no one else is saying their car is running this way using Unleashed LMS AJP BCB etc.
Those tunes are single octane purpose built. Those also require data logging, revisions and fine tuning (LMS being the exception).

The gearhead tune auto adjusts and requires no data logging. I'm bringing my experience to the table because of this unique feature. It's working as intended, unfortunately for me the fuel is causing the tune to load stock parameters.

I came across the gasket for the HPFP while searching on the New Ford Site! Z  :)
Sorry for the later reply!

Thanks! For that low of a price I may just start with replacing the gasket.

I took my car in for its normal maintenance routine, and took the necessary precaution of removing the 3 bar and putting the stock tune back on.  OAR shot to |1|.  Once I got the car back home, I put the 3 bar and Gearhead tune back on, and over the course of several days watched the OAR continue to move closer to 0. 

This week we may have some good news to share.  OAR is slowly progressing toward |1| again.  I will wait for it to sustain better than |.8|, as that should be the mapping for max boost.  Then it'll be back to the dyno!
 
I have no addressed the HPFP yet.  I think that'll be a project I'll tackle soon though.  I hope its just the gasket, though I do think Gearhead is working on supporting (or already does support) the after market HPFPs
 
No actual update to the time itself, still running the same one. It had to be the winter fuel issue. The car is quicker, and gets better gas mileage.

Trying to get it back on the Dyno for verification but nothing scheduled yet.

The fuel was the problem. The tune automatically adjusted as intended. Once better fuel was used the OAR was pegged at -1 and timing increased.

Glad I chose this tune, it seemed to work great. Only one I used.
