Yes I plan to tune the ECM for the new ratio accordingly. Any preferred tuners? I'll make/ask on a more dedicated thread for heavy details. I don't plan on using any canned Mustang tunes included with the unit, but am interested to see what's best.

I had an sct tune on my 2011 and ran ok but the tune for the crown vic are very generic . i got a tune from mart not even a week later and it,s a whole different car now
