Hello Bimmerpost!!!
Hope everyone is doing well!! We are tuning multiple G series vehicles via ecu as we speak! the removal of the ECUs takes no more than 15 minutes and no tools are require, just your hands. If you are interested in getting more power into your G05 send me PM, email (oliver@velosdesignwerks.com), or give me a call for info and availability.
Take a listen to an F90 M5 with our stage 2 tune and FI catless downpipes
