I take it you've not been following our race car build then, utilising an A3 platform but obviously with the same 2.0TFSi set up as your own S3, we are now at Stage 4 (500Bhp+) with the 3071R and fully built engine, giving us the opportunity to completely revisit this engine and tuning, with additions such as the much requested RFD in long term testing. again as mentioned above, we're also looking at adding the SPS Pro for the Audi range too, offering the adjustment of your map and switch-ability, as well as a host of other features -
Back to the software though as on your own S3, it is fully adjustable and we put the time in at the early development stages, so this is the reason we've not had to then follow up with many revisions. As for Hybrid turbos, check out the likes of TKEngineering.de and other dealers who have utilised the full adjustability to offer many different hardware set ups to their customers.
If you are having issues with your DSG, I suggest you get the car health checked, as the DSG file transforms the S3 or maybe you need to be looking at the Stage 2 DSG
