Hi All
Just found this forum
Retired automotive fuel systems engineer
Have a 2020 ST purchased from Jones Ford in Buckeye, AZ December of 2019
Live in Tonopah, AZ
Installed 5 star 93 octane tune the week after I purchased it
Have owned 6 ecoboost vehicles
all tuned
They are
2011 F150 3.5L ECOBOOST tuned with Livernois
2013 Taurus SHO 3.5L ECOBOOST with PP tuned with Livernois
2013 Flex 3.5L ECOBOOST tuned with Livernois
2016 Explorer Sport 3.5L ECOBOOST tuned with 5 Star
2018 Expedition 3.5L ECOBOOST tuned with 5 Star (still own)
2018 F 150 3.5L ECOBOOST tuned with 5 Star
2020 Explorer ST 3.0L ECOBOOST tuned with 5 star (still own)
Anyone who has experienced a recalibrated for ecoboost will never go back to stock calibration
SOOOOO MUCH BETTER!!!!!!!
