If you bought a Roush Performance supercharger for your 2015+ Mustang GT, you obviously wanted more horsepower under your hood. Well, how would you like even more horsepower from that same supercharger system for free?
â€œRoush Performance is excited to announce a free upgrade for our 2015+ Roush supercharger. Effective immediately, Roush is handing out vouchers for 43 horsepower on the house!â€ says the company. â€œThis free upgrade will take your 627 horsepower supercharger kit up to 670 horsepower. . . you heard right, free horsepower!â€
To get that boost in power from a revised calibration, youâ€™ll need to visit a web site and fill out a short survey. The web site is appropriately called AddHP.com. Yup, the free upgrade has its own site, and on that site the company does a little market research about a possible 750-horsepower supercharger system. Hmmmâ€¦
â€œIf youâ€™re currently running our 627 horsepower aftermarket kit simply visit the link below, fill out a quick survey, print your free voucher, and drive to your local Roush-authorized Ford dealership or speed shop to receive the upgraded calibration, and claim your additional 43 ponies on us (voucher is free, but calibration flash charges will apply at dealership),â€ the company explains. â€œOf course, your existing warranty (if any) remains in effect.â€
So itâ€™s not totally free, but if you can pick up 43 more horsepower and still hang on to whatâ€™s left of your warranty, itâ€™s still a pretty sweet deal.
