After a trackday, I'm certain the first turbo has changed in a way. It sounds different (more "turbo whine") when it spools from low revs and it feels like I'm lackinga bit of power (hard to tell for sure) untill the 2nd comes online.
However, according to my boost gauge, all seems well with 0,7-0,9 bar around the 3000 rom going to 1-1,1 bar when the 2nd comes online. That seems to be "business as usual".
I just have this nacking feeling that I might be a bit to sensitive but then again, I noticed it the first time I drove off driving normally.
Is it possible that something has "changed" but it still produces the same (or very close to) the same boost?
Thanks
