Have a GTR with hks 2530's & Tomei cams(unsure of specs) & bleed valve.

Doesnt come on full boost until about 6KRPM which isnt too bad pritty useable but had a look what other pple get with the same turbo's & seems 5KRPM is where they are hitting full boost?

Now i know the bleed valve is going to make it laggier but by how much? surely not 5-1000RPM?

Have checked all my vac lines etc there are lots of extra crap i need to cut-out but there are no leaks, is there anything else i should check?

Like you say a bleed valve doesn't help, but it shouldn't make that much difference.

First suspect is the extra crap on the vacuum lines. Plug it/pinch it off and or remove it - then have another check.

Other things are:

Your ignition timing.

Your fuelling.

That the waste gates are closing properly.

Cam timing.

turbos got adjustable actuators on them too?

probably not done up tight enough

I had the same problem with my 2530 on my rb20

wind in the bleed valve and adjust boost via the actuators you should need vice grips and two hands to put

the rod back on to the flap section
