What if I told you there is a way to add 100+ hp/tq to your BMW in under 45mins - you interested?

Of course! In this video we installed a Speed Buster Power Module Kit to our 2021 BMW X3M - giving it approximately 120hp and 118ft.lbs gain throughout the powerband and transforming how it feels when you step on the go-pedal!

What is a Speed Buster? The Speed-Buster Power Module is a simple plug and play S58 power upgrade with three performance modes controlled via Bluetooth app (free download via Android and Apple app stores). The Speed-Buster delivers big power gains with no downside. The installation is simple - just 3 sensors and power leads - making it the easiest power gain you'll ever do. By sending modified signals back to the engine computer, the Speed-Buster tricks the computer into safely raising the boost. And with careful programming of operational tables, the Power Module doesn't trigger torque limiters, monitors, or limp mode, which means safe power that won't kill your engine - or warranty!
