Ahkay cool beans. My turbo is a bit smaller than yours too, still not sure if I should go lower or higher because of that.

Should be getting on the dyno some night this week to throw 2 more psi at it and play with switch points

Correct me If I'm mistaken but intake should kick in first, then exhaust cam. Also have you checked timing compared to computer perceived timing?

Maybe not. The vet cams were designed so that its got maximum exhaust flow all the time. Maybe switching the exhaust first and opening up before switching the intake cam is better

As P10 Goodness said, it all depends on the setup.

I still haven't had a chance to go back to the dyno.
I did however go to the drags and went extremely disappointingly
The STi came with me and he only went 13.0@107mph, I went 14.3@105.
This was with a roll off launch, like 2.4 60' lol, then the first two runs when I changed into 2nd I got unreal wheelspin, then had to shift to 3rd and dropped to about 4000rpm, not the fastest way to do things haha.
So I'm about 5mph below where I want to be at the moment.
Unfortunately, on my 3rd run the stupid Exedy HD clutch slipped like a mofo through 1st, 2nd and 3rd. I've never smelt so much burnt clutch

So I'm taking it easy on the car for a week or so to make sure it's all good.

Then dyno tune, then new clutch, then Z32 MAF, then one of Doug's rails and ID1000s for E85.
