Matt,
I echo most other people's sentiments on here, kinda feel for ya bro'!
I think I'd definately go for my money back from Superchips too!
Your car DOES have 180BHP as standard, I know because I have the same one (Quattro[?] with engine code AJL) and I got 193 from mine after AmD fitted just my Milltek and then 227 and 238ft lbs of Torque after the Remap...
With your setup I would expect a little more than that mate!
What part of Cardiff do you live in? I'm Welsh myself but live up here for reasons unbeknown to me at this point in time! :S
I visit Cardiff quite a bit so it would be good to get together and have a pow wow sometime of your interested...
I really can recommend AmD though, they're the N*ts! In my opinion you can't travel too far to get things done properly, you only end up paying for it in the end.
Try for a refund and go see 'em mate, you won't be disappointed.
I'm not really sure how much mine is boosting because I don't have a boost gauge fitted at present but I think it's around the 1 Bar mark.
(As an aside to this topic, where is the best place to get a boost gauge gentlemen!? Options?)
And Greg, just bought an N75J for mine... where is it in the engine bay, can't seem to find it at the mo but it IS dark and I haven't had time to look properly yet...
Cheers
Tim
