Thanks for your replies guys -

Being the weekend (Friday night) I had a bit of time to do some additional "road testing".

I disconnected the battery for 15 minutes, and waited for the ECU to reset.
Then I made way to a local deserted 110kmh zone to compare 0-100 times. It was an ideal evening - still, cool, dry.
Carefully making sure there were no others at risk, I did a non stalled time - 8.9 seconds (!!!!!!)
The car was running OK, nothing had exploded, it idled OK.
I checked peak boost hold - 0.14 Bar (uh oh!)

Thoughts ran throuh my mind...
Blocked air filter, blocked cat, sensor hose leak? Turbine wheels?
I spent about 15minutes on the way home thinking of how to hide the considerable hole to be caused by a GT30/manifold/wastegate in my bank balance to my wife.......
The car still ran OK, but boost would not run over .1 bar

Giving it the once over at home, I was relieved to find the intercooler-manifold hose had slipped partially off, venting heaps of boost. After tightening it up again I was happy to get 0.9 bar after a short drive.

The moral? Check the hoses! (and the 1jz runs deceptively well without turbos)
I'll let you know how everything goes in the future.
