We installed this on our 2014 Ford Flex EcoBoost and the installation process took about 10 minutes, minus the Firewall. (The flex has a sideways engine, so we couldn't get to it easily).
We immediately noticed a silly difference in performance. The fact you can turn it off and then on again shows that it's not just Placebo.
With the BoostMax turned to max, we spun all 4 tires (Flex AWD) from a 20. This was exactly what I was looking for, since I can't tune my vehicle properly yet.
