Another update on this. I wasn't getting boost correctly at all, so did a boost pressure test. Found a leak between a coupler, but more importantly the intercooler I replaced was p*ssing air out...!!!
So I took the intercooler off RH or OS in the UK and directly tested it. It was like trying to pressurise earths atmosphere Hand

So, luckily I had ordered one from autodoc as I didn't know kozzi was going to kindly send me one at that time. It was about £350 which is a lot cheaper than from OPC and its identical. I fitted that as I was going to return it, boost pressure test up to 25psi. Held like a beast.

On to more test drives... whooooaaa steady on cowboy Mr. Green very rapid but there is a slight hesitation when its floored hard WOT, no fault codes which is a pain .
Its fine in normal driving or if gradual throttle is applied t *its been mapped as it was doing 20psi).I have been speaking to a very well respected 996/997t tuner in the USA who has been very helpful and going through the logs.

I am investigating at present and going through stuff but first on the list is O2 sensors as lambda is a bit funky on one bank. Fuel pressure is 3.5 bar at idle. No vacuum leaks.
I have been running it with live logging and will update when I get to the bottom of it. Done about 100 miles in it since it was back together, drives beautifully apart from this final niggle, will be happy to be scorching round in it in Summer
