boost solenoid fail?

[pdidily6401]

ok got to the bottom of it, evidently it is my valve springs floating as I come off a highish reving but low load with 10psi boost, going to buy some crow springs methinks, anyone out there know a reputable south island mechanic to have this done in car? I do have a spare head off the first motor so can go that way as last resort.

Hi, valve springs replaced with crow 95lb and new lifters also, notice now when I get up it that I am hitting the limiter at the 10lb boost, think I am going to need a retune, might jump up to 15lbs boost.

ok, am pretty much ready to do the conversion on the xf falcy, have bought an 04 barra complete with Turbo and trans, got the wiring loom back to firewall, ecu, and fuse box essentially everthing in the engine bay. Sooo where to go from here, can I use the original manual trans?, what engine mounts etc, should I go with upgrading the rods  while engine is is on the stand, ( will be putting in new valve springs ) any advice please, have spent the morning trawling the site trying to find a dedicated stream on this but so far no good.
