BMS JB1 Stage 1
Burger Motorsport JB1 Stage 1 plug and play tuner. Listed as suitable for N20 N26 N55 S55 but I'd advise you check compatibility before purchase. Was fitted to my N20 320i.
Gains on n20 are up to 45bhp and 60 torque. Been flawless since fitting 6 months ago. Selling due to BM3 upgrade. £125 Same as: https://www.mlperformance.co.uk/prod...5c213e68&_ss=r Last edited by GpAevo; 12-03-2019 at 03:39 PM.. |

Bought from OP and fitted.
Quicker throttle response, and more power/torque than standard. No flat spots so far after 100’, slightly better fuel economy. Better than previous tuning box I tried. |
