E9X 328i/xi N52 07-12 Stage 1 Turner Motorsport Performance Package - (NO LONGER AVAILABLE)
2007-2011 E90/E92/E93 328i Stage 1 Performance Package
Peak Power Gain: +29hp / +29ft-lbs
Rev limit: 7000
Octane: 91 or higher
Our Stage 1 kit featuring a cold-air intake kit and matching performance software. The aFe intake is a cone filter with a heat-blocking shield around it. The larger surface area of the filter, combined with the heat shield, allow more cool air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.
Our flash software is tuned especially for a cold-air intake, maximizing the potential and providing smoother power delivery. We take the stock software and make adjustments for 91 octane (stock software is set around 87). We can get more power and torque, and increase fuel efficiency without affecting driveability or the life of the engine. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.
The 328i has BMW's 'MO - Medium Output' engine so it was de-tuned slightly from its true potential. What we have done is focus on improving the mid-range torque to get back some of that lost horsepower. Since this is where most drivers spend their time these gains would prove to be the most beneficial. Both of these items are packaged and work together. They provide a solid performance boost with a built-in package discount. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice.
There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:
Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.
Turner Flash DIY tool - higher upfront cost but files are emailed back and forth. No downtime - you can still drive the car while we process your tune. Files are emailed back and forth - your stock file comes to us, a tuned file is returned to you. Easy install via Windows laptop.
