7A Exhaust cam, what does it do?

Camshaft Specs

What are the different profiles on the various cams as a matter of interest - is this information available somewhere?

Well, I did some reading and some driving and I'm now convinced that my top end power loss is not down to the 7A cam, there's plenty of evidence to the contrary in fact, I should be getting a few more bhp and better breathing with the greater lift. So on to the driving..
I found out something interesting when I was trying to read what my boost was dropping to at various rpms, basically if I floored it at 3k it will peak at about 26 -27psi, it will then drop gradually to 18 psi at 5k, sometimes less, BUT, if I lift off on the throttle and then floor it again it will go back up to 22psi and feel like its pulling properly again. In fact it will do it again at higher revs, lift off and floor it and you get renewed boost.. So what can this be? Wastegate creeping open? DV leaking? Ignition retarding? Anybody BTDT?

Maybe I should start a new thread?

I'd completely forgotten that this was the thread where I learned how to mod my car
