I really liked the old custom Jabba map that I used to run on my old turbo. Very expensive, though. I'm not sure R-Tech was around when I got that, though?!

(2005).
Nowadays, I would highly recommend the R-Tech map. This is what I now run on my spec 2 AGU 1.8T.......... Good, strong, smooth power which pulls very cleanly up the rev range.

Very keenly priced, too.

Do you know which engine code you've got?
