Nope, this was Martin from Willall's explanation of the dyno chart.
"Here is a nice comparison dyno graph - Stock B4 vs boosted GC8 2.0 with VF23 on board.  Its also auto vs manual, and the stall converter in the B4 will make the lower end torque look better than it otherwise would be. Hope that assists you with your decision "
 

^^ bingo
Not comparing apples with apples
So the comparison is crap

Tim,

Good to see a solution mate,
As always, it's the plumbing letting these things down, and shows how much difference one simple mistake can have on the entire system

[Tim.]

Yes Kong they are awesome when they are running perfectly!

The solution has been a couple months in the making so I'm happy is sorted now. The plumbing is definitely a killer in these systems but in this case converting to single wouldn't have fixed it. Singles still need a wastegate solenoid.

[Robbks]

unless you use a 15psi Actuator,
and plumb directly from compressor outlet to actuator nipple (which was one of my first suggestions for troubleshooting the problem)

[Tim.]

It ran wastegate pressure fine - 9psi all day long but they couldn't figure out why it wasn't running properly on the 15psi prior to the engine out.

You tend to always look for the most complex of reasons when troubleshooting but sometimes it's the simplest thing staring you in the face.

Can anyone tell me if all the solenoids are ment to click when in d mode? My primary boost doesn't click. And another one in the bbod

[Jimbo]

Is your TT having any problems? More specifically, what year model is it?

[Hoody]

Sure is 02 model just cleaned all the solenoids and noticed the primary boost solenoid wasn't clicking like the rest of them. Wasn't sure if it clicks or not when it d mode

[Jimbo]

Bosskong would be able to tell you. I'm not too sure, though i would assume it should?  You're definitely checking the right solenoid? Your primary boost control solenoid is located on the other side of the fender where your battery is, in your passenger wheel well.

What problems are you having?

[Hoody]

Yeah got the right one. Ok cheers. I can only get 0.5 bar of boost

[Hoody]

Thanks for the reply. Na no codes. I'm in Newcastle but I'm busy doing renos:(. Yes it has I fitted a gfb which got my boost up to 0.5

[Hoody]

Wow yep I've got the wrong way (stock way)
I only bought the car 4 months ago do I don't know how much love she got.
The cel light works but.
Took the intercooler off today to have a look around notice I have lots of blow by.

[Hoody]

Well I cleaned all my vac lines n now my primary turbo isn't working my car is very sluggish until the second turbo kicks in. Such a head fork I checked all the hoses in the bbod n there all connected. On the bov plumbing the pill doesn't go back in? With the new line

[Jimbo]

No, just have a straight line from the manifold to the BOV. If you put the pill back in, your BOV will leak all your boost out. Did you put the pill back in?

Did you make sure you put the intercooler back on correctly? It's a bitch to get on and off and sometimes while you may think the primary hose is on properly, in some cases it has pinched on the side you can't see and not on 100%.

Triple check all your vac lines are where they should be by cross-referencing it with Boss's check diagram.

[Hoody]

Ok first photo is the bov I have it hooked up wrong cause I have the bleed line still on and the pill is in there.
Next is the primary turbo actuator line it has the pill in it
Last photo is the bbod
I've checked the intercooler everything looks tight
