BMW M140i (2017) – developed 335 to 430bhp with torque 369 to 493 Lbft.

Celtic Tuning have recently developed a very healthy stage 1 for the B58 engine fitted to the M140i and M240i engines – now delivering a massive performance improvement.

I have driven a few of these and the results are astounding, for just a software only modification….

There is also a Stage 2 available on the B58 – where a Decat exhaust has been fitted @ 455 bhp.
