As she sits now, max is 16.6 or something that I got, at about 3500 revs, in 4th.
Definitely not limp mode , as I do HAVE a lot of power, up top end of 4th and 5th. If I step on it in 4th, after it spools up, to above 2500RPM, she goes like theres no tomorrow. The boost maxes out but she keeps on gaining speed no dramas.
It's the spooling up at low end thats the issue.
So here is my typical scenario.... (once car is full warm)
1st - take off rev it till 2600-3000, change to 2nd, rev till about same, 2600 - 3000, change to third...
Now out of third no matter what I rev it to, once I change to 4th, revs and boost drop and she just sits here labouring and slowly winding its way up.
As mentioned above, once up top end, power is there.

I'll take it all apart on weekend, or wait till mudski is back in town and free. The car is driveable no dramas, but I know it CAN be and WAS 10 times better till I (dont even know why) I decided to touch it... as I didnt think it would throw it all out of whack.

RJ is probably right as he is a bit of a guru, if it was me in your shoes from what you just described I would close off my needle valve more, I found with mine,which mudski also set up and I wished I never touched it cause he had it going awesome, that if I adjusted one valve it did effect the other even though it shouldn't. So if you close your needle valve off a bit your turbo should spool up quicker, the worst thing that can happen is you hit limp mode then you know you have gone that lil bit too far

How did you go
got it sorted did you ?

I sort of got it better, but still not like it was. Will catch up with mudski when hes free. Even if 2 of us, can't get it right it's got to get a second opinion/driver, to prove it's not just me.
