Last night i had my manual boost controller set too 1 bar. After a bit of fun it spiked to 1.2 bar and then no more boost. At low revs about 2.5k you can hear the turbo spooling up which i think its the 2nd one. As the first one normally sounds much louder when it spools up.

In 1st and 2nd gear their is no boost at low/medium revs, In high revs it boost too 0.1 bar. in 3rd gear it boost too 0.2 bar sometimes at 3K RPM.

I am so confused i aint sure if i have blown a turbo or whats going on. I check all the intercooler piping everything looks ok. And vacuum pipes.

Could i have blown a turbo? or 2?
