Grudge Motorsports Racing has teamed up with Demon Performance for the GMR Redeye'd Hellboy Pkg install & tune! GMR + Demonized = Redeye'd Hellboy

We have configured this package to make enough power to drop down into the 8's while retaining complete streetability and full interior. Stay tuned for updates and to see how much power the GMR Redeye'd Hellboy package can make in our demonized Hellcat Redeye Challenger!!!
