hey, ive heard this noise a fair bit, just wondering if anyone knows what makes it

its like a highpitches whistle on gear change, is it the Blow off valve or wastegate or is it compressor surge or something else...

Thanks for clearing that up. Saw it go from 100 to 130 in what seemed about half of a second...

ssqv. sounds just like mine.
my brother has a greddy type-s on his stealth and it sounds nothing like that.

That's MPH. Most 'busas came factory with a 220 mph speedo, but maxed out in the 180's. If that was KPH, he would only be doing about 120mph @ an indicated 200kph.
