BimmerWorld Stage 4 Power Pack - F22 228i

• Power Gain: 51hp
• Torque Gain: 81ft-lbs

This package of flash software and cold-air intake not only delivers impressive power gains on paper but it makes a bigger impression behind the wheel!

With flash software instead of the piggyback, we have full access and control over multiple maps for fuel, ignition timing, camshaft and VANOS control, boost pressure, torque limiters, throttle response, and others. These are maps that any piggyback module simply can't touch or control. Most importantly, we do not modify or disable any of the factory safeguards built into the software. This ensures that overboost and knock monitoring remain in place for maximum protection. Our software was developed with Epic Motorsports on multiple cars and dynos at the same time as our N20 Big Turbo package (Stage 5). We also incorporated our hard-won knowledge from five years of racing the F30 328i in the Continental Tire Sports Car Challenge series - no other BMW tuning and parts company has more experience with this model on the racetrack.

The Injen Evolution intake fits with our belief that solid engineering and testing produces the best performance. Injen engineers design their intakes to carefully manage air velocity and air pressure using the Venturi Effect and velocity stacks. They also used the largest filter they could fit in the stock locations. With greater surface area and better flow there is more air available to make more power. Not only were we impressed with the quality and fitment of this intake but it actually made power on the BimmerWorld dyno.

A better front mount intercooler is strongly recommended with this package.
