Hi All
75 years old here
So I am also in the "OLD FART" category
Have owned 6 ecoboost vehicles
All were tuned
First 3 with LMS
Last 4 with 5 star
Currently running an E30 tune in our 2020 ST
Runs like a Bat Outa Hell
Who is ZFG
Not familiar with them or what they offer
Wonder if the ZFG 93 octane tune would be equivalent to the 5 star E30 tune
