N55 Stage 2 Tuning package Inc. Installation (suitable for M135i M235i 335i 435i 535i)

The GTS Tuning Stage 2 remap package for the N55 engine commonly used in the M135i M235i 335i 435i 535i models. Includes the following components:

  • K&N Air Filter
  • MTC Catless Downpipe
  • Genuine BMW Downpipe Gasket
  • Bootmod3 Stage 2 Tune
  • Upgraded Silicone Intake Pipe
  • MTC Motorsport aluminum Charge pipe
  • MTC Motorsport upgraded intercooler

Our Stage 2 package offers impressive performance enhancements, providing up to 420 Bhp and 610 Nm on premium (97+ octane) fuel. This upgrade also unleashes the true raspy tone of the N55 engine, whilst maintaining its refinement. Comparatively, the factory figures stand at 315bhp and 450NM.

The K&N free-flowing air filter and upgraded silicone intake pipe ensure continuous supply of cool air to the airbox. MTC’s 4″ stainless steel downpipe (Sports cat options available on request) significantly reduces exhaust back pressure. To prevent boost leaks and enhance flow to the intake manifold, we recommend a MTC charge pipe and MTC intercooler. By combining these hardware upgrades with the tried and tested BootMod3 stage 2 tune, the results are remarkable.

xHP gearbox software also recommended for automatic vehicles, to lift transmission torque limiters.

Original price was: £2,560.00.Current price is: £2,200.00.
