Wanted- performance chip 164 motronic

[camwright]

I'm looking for anyone who could sell me a Performance chip for a 164 3.0L V6 motronic ECU. It is running in my GTV6 with the only engine mods being enlarged intake runners and waggot cams. I've been stuffed around by overseas 'gurus' before so keen to keep it local. Any advise on where to get a decent one would be much appreciated as well.
Cheers, Cameron.
