About this file
Stage 2 on the 320i goes further than Stage 1 and expects supporting parts: a freer exhaust or downpipe, a bigger intercooler and a clutch rated for the torque. Fit them first; on a standard car a Stage 2 file asks more than the parts give.
The BMW E30 320i carries the 320i engine, 129 hp and 164 Nm from the factory. On this engine, Stage 1 usually gives about 141 hp and 180 Nm (+12 hp, +16 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For this calibration of the BMW E30 320i we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
