Little Update: Took the car to the mechanics to see if they could determine what the boosting problem was. They disconnected the wastegate and it built boost all the way to boost cut, which the gauge indicated was around 10psi. I've been told that boost cut on these should be around 13-14, if someone could confirm that'll be awesome. Mechanic seems to think the gauge is faulty and displaying different pressures now and then which causes my placebo of feeling faster or slower. I might have to hunt to see if the vac line is kinked anywhere or try and find another boost gauge to test it. 

Did a little digging on this after you sent me a massage about it, and this is what I came up with
 
Stock boost is around 10psi.
Jdm car, gen2 the fuel cut in the late 91-93 models (15/16psi).
Jdm gen3, stock boost is 13psi, fuel cut around 18/19psi.
 
Hope that helps.

yep that fuel cut is correct, I have a hks fuel cut defender on my car and it works great, had the boost at 16 psi until I blew the stock turbo now I just run 12psi, I have another hks fuel cut defender if youd like to buy it

Thanks so much Nik_Lee,
 
I bought a GFB Electronic Boost Controller on the Weekend so this'll sort out my boost issues and I'll get someone in the know to tune it in for me so I can get a much nicer boost curve and more power! I'll probably set the Scramble to 13psi and the normal to 10 or 12psi and gradually change the settings. I'm pretty excited. 
 

Any update on this, have you had it fitted yet and have you noticed a difference?

Sadly it's still on my desk, been too busy with Uni to even do an oil change. Although today I managed to get up super early and fix a broken engine mount so thats good. Also confirmed that my boost guage is fine and something must be up with the VSV so I'll get it installed soon I hope. 

Are you planning to install yourself?

I'd like to seeing as its a fairly straightforward install but I may get either friends or Denstoj to do it, then I need Ben Perry's Dyno to tune it in to fix the boost curves. 

Well there has been a spanner in the works, on Monday night the car made some god awful noises and I now know this was the drivers side front sway bar mount ripping itself from the chassis. It probably didn't help that I installed brand new end links and did old pac twice on the weekend. Noise got progressively worse over the next 4 hours so I took it to my legendary mechanic who showed me how bad it was then welded up some replacement metal and then welded in some reinforcement plates so it's much stronger now than it would be with the plates that I would have got if DeltaV didn't run out of stock.

Fark! That's a huge hole!
