WGM Stage 2 Tuning Package for BMW M3 / M4 equipped with the S55 Engine (430/450PS model)

An impressive 130HP+ with 100LBFT+ midrange gains can be seen from this must-have package! Our Road and Track proven ECU software calibration takes the M3/M4 to another level boasting up to 560HP

This package is designed for those seeking an improved soundtrack to their engine while picking up some extra horsepower also, turbo spool and low-end response will be dramatically improved from the free-flowing downpipes – for those wanting to retain road legal (MOT) status, we advise leaving the secondary factory catalysts will still pass UK emission tests. Otherwise, for optimal gains, secondary catless pipes should be installed!

We have chosen to select the Enhance Performance downpipes, due to their superior quality and manufacturing process here in the UK. These are unrivalled with fully back purged TIG welded products which also look as good as they are made! We can supply other downpipes, but we choose quality before price.

With this tuning package, there are a few options;  

– High flow air filter drops in place of the standard paper filter into the standard airbox, we offer K&N filters for this application. Crank hub capture plate can also be offered at this point.

Uprated Airtec Chargecooler / Charge pipes are also offered for improved charge temps, ensuring power is consistent lap after lap on track and street while removing the noticeable power drop in the summer months! 

– Cat-back back systems can be offered, enhancing the soundtrack while keeping the GPF Filter in place (2019 M4 only) retaining a full road legal set up.

  • Roading Road (Dyno Session)
