I love my mega and I often flash new builds and ROM's. Since day 1 I always flashed the PurePerformances MOD. It really works and it is really worth looking at the original thread. I do not own any credit of this MOD, I just wanted to share it with you, my fellow mega-fans.

PS: I would love to thank @Jeeko
to make this mod happen. Don't forget to give a ''thanks'' on his post!
