Trying to find a few other fellow S4 owners who have the O.CT kit but there doesn't seem to be any ?? What gives ?

Would love to talk with anyone who has gone to a stage 6 S4 kit, larger head gaskets, RS4 turbo's, MAF etc etc etc. Have an issue with Throttle cut at 6200 rpms and would like to find out if any other O.CT owners have witnessed the same thing and what they did about it.
