I've had a lot of trouble, I went to the doctors though.

Check your thread title.

Did it make a strange noise like a fart when the anal valve broke?

Best typo I've seen for a while
did it happen when you applied pressure (boost) to the thin tube at the end not attached to the other pipe work.....
some times you need one of those restrictor rings round it to stop it blowing off....
If you use a tie wrap you can have some dire consequences when there pressure build up is too much! LOL

Wrong jetting of the Amal valve can cause this.

If you have very little or no restriction in the C-Port and more restriction in the R-Port then that can put stress on the valve.

It's better to have most of the restriction in the C-Port, this also give more midrange boost as it delays the signal to the actuator.

Thanks Guinnless for that explanation. I'm gonna ditch the valve in favor of a boost controller I've just got from msd
