Steve,
Sorry to burst your bubble - you wont see 60bhp from a stage one remap (unless you have an Edition 30?). from a 'normal GTI, 35-40bhp is typical). A good remap on an Edition 30 should see 290-300bhp with V-Power fuel.
AMD's dyno is famous for giving high readings compared to other dynos, which may be why they claim such magnificent figures. AMD intake is far from the best intake - your better off with either EVOMS or Revo intake. The Ram Air intake is OK too.
Finally, AMD remaps are fine - they're safe & give reasonable figures, but the tuning game has moved on since they wrote their maps back in 2005, and dyno days recently show stronger curves and better peak figures than AMDs maps from other competitiors. Have a look around the modifications section of the forum - the popular tuners have their own section with lots of feedback & results. R-Tech are the most popular currently - and the results speak for themselves
