Thank u Jez, the tune went great, its running smooth as ever, as you mentioned, need a 3" hiflow cat, turbo-manifold gasket, (dump pipe maybe later) and a re-tune on the dyno for power figures, ign timing maps, more boost, knocking and tuning 4th and 5th gear tuning. And I gotta fix that fuel tank seal as well. So many things to do, need to get it out of my head asap.
I recommend Jez AA++. If any of you thinking of getting a tune(Nistune, Power FC, Haltech) or any electrical / mechanical work, he is one top bloke, DVS Tuning located at Central Coast. Check him out, he was awesome to deal with, +1.
Thanks again mate, you did a great job.
