This performance chip is made specifically for the 731 or 885 head on the B27 2.7L 325e block with Motronic 1.1/1.3 upgrade. Typically this is referred to as a “frankenstein” engine, M20B25+27, “stroker” motor, “2.7i”, or “327i”.
This chip is also intended specifically for use with the M30 VAM (AFM). The M30 VAM (vane air meter) requires a different sensor calibration than the stock M20 VAM, and therefore requires a specific tune.
Bring your M20 to life with this fully tuned, daily driven, and track tested performance chip. The SSSquid Tuning performance chip is the most complete tune on the market, with every aspect of the mapping being optimized from idle to wide-open-throttle.
