welcome to the forum, make sure you get onto gman for a remap, it costs $400, and is byfar the best upgrade for $$$ for the turbo's.
also there is a newcastle meet up next weekend, try n get along. it's a great chance to meet some of the members .

hey, if you interesested in the tune and wanna talk bout it, i will most likely be at the newcastle meet, and can answer some of your questions
and if you were keen i may be able to flash it for you, and just pass on the funds to gman, as it's his area for the turbo's, i would have to confirm this with him 1st of coarse.
gman is constantly traveling between oz and hong kong.
