OK, lets talk EcoBoost tunes....
I noticed on the Diablo website that the 93 tune requires/recommends spark plug upgrade. Are there any issues with Not upgrading plugs? Was the tune tested with stock plugs? Thanks
The 87 tune will work fine on the stock plugs, but the premium tunes may lead to some spark blowout if the plugs are not upgraded on the 11-12 models.
Thanks
