I thought Dan Kyle had a map available? I think he does. It isn't for the TRE but in my uses the TRE maps arent' that much different. i believe the TRE is for below 5500 rpms so just dont be there expept in first and you are all good.
I also have a TRE but just a slip on so without busting out for a true custom map, I haven't felt the need for a PC3. Maybe if I had a full exhaust I'd be more tempted but I'd want a custom map either way.
