I must admit I haven't but I can't see how that would make it over-fuel or am I missing something?

Could the dump valve being leaking, AFM measure X air going in, but Y air has been bled off, thus making it rich?

Well I've been speaking to Barbz and we think it may be the temp sensor or stat as my temp never gets beyond 70c. Ok it's really cold out but perhaps that could be keeping it on the cold start map?

Right I removed all plugs today and checked wiring to coilpacks and injectors.
Wiring all looks fine from what I can see, the plugs are all burning the same, they're all very black which indicates the over-fuelling but as said they're all identical condition.
I've got a brand new temp sensor and thermostat going on tomorrow. Any other ideas?

I checked all the coilpacks and all plugs are burning the same hence I assumed this meant coils are fine too?

Hi,
have you measured the fuel pressure? My friend here in Finland did have similar problem, his car didn't pass our MOT due to a too high emission values.
Reason was found from Bosch fuel pressure regulator, spring wasn't able to keep fuel pressure low enough in low rpm. With vacuum hose connected, fuel pressure was almost 4 bar when engine idling.
He changed a new fuel pressure regulator and problem was solved. I would try original 3.0 bar regulator, you shouldn't need 3.8 bar regulator until you are going above 350 bhp.

Ok JBT, shall I swap 2 out, drive it, see if it changes etc. Then swap another 2? (I only have 2 lol)
Jari how can I test fuel pressure?

Why was the non-standard FPR fitted and was it before or after the mapping?

It had a 3.8 bar fpr fitted the same time as the stage 3 hybrid etc and then was mapped.

Big update! With the help of Barbz and some further investigating I discovered my temp gauge never went above 70 degrees no matter what. So with this in mind we figured the stat may have been keeping the car on the cold-start map which runs a lot richer. So a new thermostat and temp sensor was purchased and armed with my tools I set to work. Casually went to unbolt the main boost hose connecting to the throttle body only to find this... I immediately sent this photo to Barbz and we both jumped for joy. I did think to myself, hold on I had a smoke/boost leak test performed but then I remembered it was capped off after that hose so never would have shown! *Face-Palm* Fishing around in my friend's garage we found some silicone perfect for the job of replacing the pipe and fitted it snug. Seeing as I knew I still had a thermostat fault I still went and performed the thermostat removal and replacement which, overall, wasn't too bad a job, even for a novice (me lol) Then I fitted the pipework all back on and securely fastened everything and ran the car up to temp with the cap off, bled the system and replaced the cap and was delighted with my new temp gauge reading... I then took the car for a road-test and words cannot describe the difference now the car is actually generating boost pressure. My face resembled this on the first plant of the loud pedal - The Stage 3 hybrid setup is astonishing and I'd definitely say Barbz has done a spot on job of mapping it as the power is relentless and power is available from 2800rpm to 7000rpm and the boost pressure never tails (1.35 bar). The car is transformed and I'm over the moon. Barbz says with a decent EBC it may even be even faster...scary stuff. A great result finally, thanks for everyone for helping along the way!

So is it mapped via a UNI chip then?

Maybe time to look at getting the rest of the boost hoses replaced.
With the age of our cars many of the hoses are becoming worn and tired.
Coupe now sold!

I presume you will get the mapping redone? No need because when it was mapped, (6 months ago or so) the pipework was fine or Barbz would have spotted it. I'm going to go for silicone boost hoses everywhere soon as an upgrade. Poor cars are aging!

Great result! I have heard a lot about Barbz and could use him for my current setup which is similar to yours. Could you provide his details please?

Oh definitely, once I have the EBC installed I'll be having it dyno'd again and tweaked by Barbz on his return.

Well as some of you may or may not know I've been having problems with my 20vt and it's never felt anywhere near as fast as it should and bogging down a lot. I presume you will get the mapping redone? No need because when it was mapped, (6 months ago or so) the pipework was fine or Barbz would have spotted it. I'm going to go for silicone boost hoses everywhere soon as an upgrade. Poor cars are aging! I'm sure it's not just me thinking this, but if it was fine 6 months ago, it would have gone like a stage 3 should have. Wouldn't it? You said it never felt as fast as it should and that would imply that it wasn't running properly then. If it did have a leak back then and was mapped with it, then the map will likely be out now, hence the reason (excuse ) for a dyno run to re-check the fuelling. I'd put it back on there just in case...
F****** b****** thing...
