Do you guys not think compressor surge may be a bit of a problem?

 

OK so you are driving down the road at 1.3 bar & you lift off the throttle, so it slams shut. Where does all that pressure go?

 

I'll tell ya where it goes, it backs up the pipe, causing either:

Turbo stall, Vain Stripping, Shaft Snapping or twist, or blown off hoses...... shall I go on?

Yep, spot on, it's an eaily policed, simple and reliable means of forcing every engine to run to the same maximum boost pressure.

This gets better.

 

2 No. Wastegates both plumbed in with no vacuum source. So no BOV & no way of actually controlling the Wastegate/s.

Mmmm, nice job. Without this bbs recommending competent people, any one of us could have ended up having cars "tuned" by monkeys like this. Surely the owner must have noticed something was up though? I mean, if you paid someone to come and fit a washing machine and you ended up with something that incinerated your clothes and flooded your kitchen, you wouldn't go "oh, well done chap, here's your money", then think about getting a second opinion two weeks later . . .

It's called "Trust" Adam & is sometimes severely misplaced or abused.
