Here is a video of my car - GT28 running about 1.1 or 1.2 bar at the time. (now runs 1.5bar of boost)

Crap camera, my car is a lot deeper sounding in the flesh... like an evo.

 
Looks like you got abit out of shape there lol. Does sound nice what exhaust you running?
 
Its a 3" turbo back system with just a small backbox and 4" tailpipe, custom made by a local exhaust company. Its very loud, but sounds amazing on boost, video does'nt really do it justice tbh.

Lol yeh car was harder to control at the time as it was still on standard suspension. So cornering at full boost was/can be an issue! pmsl
