Our Stage software for the N52B30 engine in the E90 325i/330i, E60 525i/530i, and E85 Z4 3.0i/3.0si has been tuned for above 330i spec. This tune is for stock 330i/530i/Z4 3.0si or for 325i/525i/Z4 3.0i with the 330i intake manifold upgrade. This brings the N52 engine up to N52B30O0 spec and beyond. The original factory software in your BMW has been engineered for emissions compliance and mass market appeal, leaving performance out of the equation.

Our Stage 2 software optimizes engine output when in 330-spec plus basic cold-air intake and cat-back exhaust mods. BMW deliberately de-tunes their cars for the lower octane that we have in the US. This naturally leaves some room for improvement if you only run 91 or higher octane fuel. We tune the ignition, camshaft, and VANOS values to optimize them for better fuel. We also adjust the fuel maps to match the more aggressive timing and remove or raise the artificial torque limiters. Our software produces more horsepower and torque and a smoother-running engine. We don't just tune for full throttle either - there is more torque available in the mid-RPM as well! Throttle response is also improved.

We have been partners with Epic Motorsports for BMW performance software for over ten years. They are one of the very best BMW ECU tuners in North America. Our custom performance tune for the 325i/330i/525i/530i/Z4 combines these years of BMW performance tuning, racing and track events, and ECU tuning into this fantastic N52 software upgrade.

Our software is installed via the Engine Calibration Interface (ECI) and your Windows laptop (compatible with XP, Win7, Win8, and Win10). The ECI cable is included at this price. Read and email your stock file and a tuned file will be returned to you. This is better than off-the-shelf tunes that never look at your original software.
