Description

This is an ECU remap specifically designed for the BMW E8X 135i & E9X 335i with the N54 engine by Xatrix. It is not an off-the-shelf remap and is specifically customised to your N54 powered 135i & 335i.   For track and street use, power delivery is smooth, sharp, and consistent, our development focus on drivability for an OEM like power delivery, and not just peak power.  Suitable  for models that already a downpipe, intake, chargepipe and intercooler installed.
