- Power Gain: 22hp
- Torque Gain: 22ft-lbs
Power upgrades are wasted if heat soak and high intake temperatures are robbing the power. Higher boost levels can overwhelm the stock intercooler which is why our Stage 1+ kit for the F30 328i pairs a Speed-Buster Tuning Module with a larger and more efficient CSF Front Mount Intercooler. Both pieces are simple plug-and-play upgrades with proven results. The Speed-Buster plugs into your existing engine wiring harness and the FMIC is a direct replacement for the stock piece. No permanent modifications are needed and they can be removed at any time.
The Speed-Buster Power Module is a simple plug and play F30 328i power upgrade that 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!
Inside the Speed-Buster module is a sophisticated programming module, tuned specifically for the N20 engine on Speed-Buster's MAHA dyno. All development, tuning, and production are done in-house at their German facility. Speed-Buster's programming works seamlessly with the factory ECU to give an impressive increase in power with factory-levels of driveability and smoothness. All factory overboost protections remain in place and the system can be uninstalled at any time. A bypass plug is also included that allows stock operation without component removal if you want your BMW to appear stock. The Power Module works independently from the factory BMW ECU so it's unaffected by software updates and revisions, and all OBD diagnostics and service functions are untouched.
CSF is an OEM supplier for radiators, oil coolers, intercoolers for many industries, including automotive. With a larger core, the CSF F30 FMIC does a better job of cooling the intake air to make more power. This cooler is so efficient at cooling the intake air that CSF saw repeated 15-20hp gains on a stock 335i with no other changes. The CSF Intercooler for the N20 engine is two intercoolers merged into one larger unit. The standard oversized intercooler is augmented by a taller intercooler in front. This maximizes the available surface area but does not require any modifications for installation. It uses all of the factory connections and install points for a plug and play fitment. CSF includes a lifetime warranty from defects.
While this package does not add any more power than the Speed-Buster on its own, it provides a more robust cooling system to help prevent power-robbing corrections from higher intake air temps and heat soak. A stock intercooler may become overwhelmed, leading to higher intake air temps which will cause the engine computer to cut power. Having a larger intercooler is extra protection, especially if more tuning is planned down the road.Notice of Emissions Non-Compliance.
