The S58 platform has been a proven powerhouse since its original release in the X3M. The only thing holding many owners back from unleashing the true potential is the unlocking process of the DME. With the help of the DAHLer ECU module, the lengthy process of removing the DME and sending it overseas is negated! Paired with the DAHLer exhaust valve controller and our PSI G87 Midpipe, this whole combo helps release the true sound and potential of these S58s.

Why didn't you show the installation of the Dahler?

You said you'd show the install on video. Come on - post the video of the installation.

That CF diffuser really enhances the look of the rear end.

Sounds like the DAHLer ECU module & exhaust valve are great new offerings. However, I would like to see some in depth long term reviews after this unit has been paired with the S58 after a year or two, just in case for longevity compatibility concerns. Wish there was an easy way to see all & compare ALL the different ECU mods, all bolted to the same car on the same day or over the course a few days to really see the difference. It's hard to know what's fundamentally different from a software algorithm standpoint.

Is the Dahler essentially another variation of piggyback?
