I've switched to my 91 tune but that was after my Bluetooth adapter took a crap.SHOnUup said:Says no e/20 - e/85 in the fuel door...still within parameters with a small mix...
If anyone tries the 91 tune, that would add to the info here though.

I have been watching timing advance with my x4. Seems to be dropping less with the 91 tune running 93 gas.
