Do you know if TVS limit the torque a little, regardless? 415bhp and 560nm is quite interesting - mine peaked at 350bhp and 540nm before we took it down to a more sensible 330/490. That's an EA888.3 with some hardware and a TCU tune. Frankly I think you should be doing a TCU tune with any ECU tune, but that's just me. Anything stage 2+ I'd also be looking into some physical gearbox stuff - DSG boxes are great, but when they do go bang, they really do go bang. It is quite interesting that TVS don't mention their sintered clutches or anything, even on their stage 3/4 pages. The Golf Mk9 is en electric model, with the Cupra Leon/Formentor, vRS, etc almost bound to follow suit. The end for these cars isn't near, it's here. They did announce the EA888.5 not too long ago, so fingers crossed Cupra/Skoda/Audi will get their hands on them, as otherwise it's only available in this sack of sh-, er, joy.
