F150 Shelby pulley upgrade and tune suggestions???
I was wondering if anybody on here has any info on if there is a good pulley upgrade and tune option out there to get the HP to the wheel as close to the number they place on the badges i.e. the 2018 says 755HP on the badges when thats to the flywheel not to the tires. Any info would be appreciated.
Thank you.
Thank you.
