Is there anything else I should check?
I've changed the pcv unit but not the rear metal pipe yet. Also my thermostat is sticking.

Ok, might have been a bit premature in my assessment. Not sure if it took more than 1 journey for the car to reset any errors it had but it seemed a fair bit quicker this morning. I know it was damp but I was spinning the wheels in THIRD! Made me chuckle....3rd?! What tyres are you on? k03 or k04? Remapped?
Anyway, I had a new Rev G fitted a couple of months ago, and it did seem to 'adapt' after a few days of driving.
Fwiw.. mine is a k03, Stage 1 R-Tech, with Michelin Supersports, and it sometimes spins up in 2nd. That's in a straight line, on a good surface. I'm sure it'd spin up in 3rd if I gave it the beans round a bend, but I try not to
Sounds like you're getting healthy boost now.
Edit: Just saw you said DAMP. That explains it!

Tyres are amazing - Kenda Kaiser!!! Sadly they are brand new put on before I bought it. I am trying to kill them asap although to be fair in the dry they are pretty grippy, they just make a hell of a noise and are a bit loose in the wet. Not the worst in the world but I want Eagle F1's again which I loved on the 325.
Turbo is a standard K03. Before I fitted the dv replacement I didn't used to get wheel spin, even in the damp.

There appears to be no solution that works with each setup.

Consensus of respected tuners and forum members is Rev G, treated as a consumable, and replaced at service time or at least every couple of years.
It's not a big job or an expensive part.
You shouldn't really look at it as 'fit and forget', especially on a remapped car.

At least if you've got a rev G it'll be obvious it's split. And you know you'll be getting full boost with a new one.
With a rev D, I'd personally always have that nagging doubt that I was losing a few PSI, as much as it was 'working'.

Seems nuts to me that people are accepting that a 12 month service should also include £35 of cam follower and £45 of dv every year?! That makes the Golf GTI hot hatch very expensive to maintain in my opinion considering it is only 200bhp and not an absolute premium brand....

Although I don't think the follower would need replacing that often. Maybe if you have an uprated pump.
Someone probably did say the D is preferred for mapping. And they're as right or wrong as someone saying the G is preferred!
I chose the G after reading up as much as I could and trying to make an informed decision, and so far in my case it's been fine.
I'm sure there are plenty running the rev D without issue too.
They're two different designs built to achieve the same function. So I guess opinion will always be somewhat split.

On Friday I changed to a rev g and my mechanic informed me that the rev d fell to bits when he was getting it off the car. It was only fitted a month ago (although I had done 5000 miles in that month). I have the rev g fitted and after 2 days its starting to pull a lot better. And a lot more consistently.
I am already quite accustomed to the power though. I have always thought that 200bhp in a 2ltr is the low end of enjoyable performance. I had a 1.8 170bhp TFSI audi A4 for a bit and I actually enjoyed the power delivery from that more than the golf. I feel like I have to work for the performance in the golf where as the audi everything just felt effortless. Holy crap I'm rambling again.

I'm in the Jap scene as my weekend toy is a 275bhp MR2 Turbo. How come the likes of 1000bhp Supras running £150 an HKS SSQV 2 blow off valve don't have this level of issue. It's madness.
My second hand £60 SSQV2 must be a good 10 - 15 years old and holds boost perfectly.

Replacing a £40 component with every service is nuts in my opinion. Especially with the £35 cam follower that some people are also replacing at every service (also nuts).

It's generally a K03 GTI issue, as the DV is slapped right up against the turbo, especially noticeable on tuned K03 due to the increase in temps.... the diaphragm version DV's split due to the heat, the K04 turbo'd GTI's have the DV relocated in the engine bay and don't suffer anywhere near as much.
There is a relocation kit available for the K03.
