I installed it on my Mega. Positively see no changes or anything faster.. all same, same app launch times, same times for copy paste or move files around, same benchmarks, same gui speed, same everything.. nice try but pointless. I am yet to EVER see any script or "speed booster" app that ever does actually anything. It's down to processor speed and available RAM.
I have a custom kernel installed on my stock ROM and allows over clocking the CPU from stock 1.7GHz to 2.1GHz.. folks, that's the real speed booster..
Everything else is imaginary.. period.
