991.1 GT3 ecu flash
Anyone have soft tonic tune? Claims 515hp w 93 octane. Huge gain. Irresistible. Have the brombacher side muffler delete and figuring do the bmx race filters and this ecu flash and be done with it. Have heard there might be reliability issue w this motor tho for track use. Car has 6k Sunday driver miles. Figuring 1000 track miles before I trade for a 992 gt3 when it comes out. Don’t want to have an engine problem or warranty issue if it is a genuine concern.
