RacingLine has been developing high quality performance hardware parts for nearly two decades - firmly establishing themselves as the hardware brand of choice for Volkswagen Group vehicles.  But they aren’t stopping there.


They have been working flat out over the past two years to develop their OEM+ Performance Software. We believe it to be simply the best ECU Software Upgrades and TCU DSG Transmission Software on the market for VAG vehicles, conceived from a very different approach. By bringing together a full suite of carefully developed software, all matched to work in perfect harmony with their ever-growing range of hardware, we truly believe that RacingLine Performance can offer customers the most complete range of upgrades for their VWG cars.

OEM+ is offered in different ‘Stages’ with each stage giving increasing power outputs over the last. The simple format is that Stage 1 works on a completely standard car with no other modifications needed. Stage 2 then delivers higher power, and needs a high flow intake plus a high flow catalyst fitted. Then for those models on which they offer a Stage 3 option, that also requires an uprated turbocharger and other parts. Any required hardware parts that you’ll require will be advised by our team of engineers at MMR Performance.


It goes without saying that we recommend RacingLine Performance Parts hardware to go with their OEM+ software! They have done all of their calibration development to get the most from their own hardware at each stage and ensure everything matches perfectly. However, it’s not an exclusive deal – as long as you have chosen quality rival products for your hardware choice, OEM+ will still delight you!
