Had a 620mile round trip this weekend to Essex and back. Was a really good day though.
I travelled down on Saturday and stopped in a hotel overnight with the missus. Gave the car a clean up when I got down.
I had a great day, massive turnout and it was great to meet people off here who I normally only talk to on the forum.
Looking through my pics I only seem to have taken pics of the bay the night before (in the dark) after cleaning up the charge pipe and manifold:
RR day pics:
On the rollers:
My mottor seemed to be getting some attention and got some good comments about it, so happy days.
Car made 297bhp 352lb/ft. Main things done since it was last on the rollers are:
Service
New sparkplugs gapped to 0.035
2.0t coilpacks
Badger 5 V2 TIP
MAF
N75 E valve
Forge 008
Catch can with 19mm inlets
Cleaned up the K&N
Happy with the figures but the 1st run (when these figure were achieved) was all over the place, I'll get a pic up tomorrow. The second run was alot smoother and it made 290bhp 324lb/ft, I'm going to put the way the first graph went to being first on the rollers but I have no doubt the car is capable of producing those figures again with a smoother curve. I may have to go back to motorscope to get it on thier rollers.
Only downside was on the way home just south of Leeds the car missfired and threw up two fault codes:
Obviously I had to get home so pulled over and gave the car a rest while I looked them up. Cleared the codes and put the missfie count up on the screen of the liquid gauge and carried on home. I didnt get any more missfires and the car seemed to be running spoton so, not sure what it could be. Any advice is appreciated.

Code:

[B]Possible Causes [/B]
Air Intake System leaking

[B]Special Notes [/B]
This DTC indicates that one or multiple cylinders are misfiring, but the ECU fails to identify the cylinder.
[B]16688/P0304/000772 - Cylinder 4 Misfire Detected [/B]
[B]Possible Causes [/B]
Ignition system
Fuel injectors
Fuel pressure
Running out of fuel
EVAP canister purge valve
Evaporative emission system
Low compression
Base engine problems
Controle Module damaged
[B]Special Notes [/B]
This feature search for engine misfire in a specific cylinder. Most of the time the cause for a misfire is a lack of combustion in a cylinder due to absence of spark, poor fuel metering, or poor compression.Obviously I had to get home so pulled over and gave the car a rest while I looked them up. Cleared the codes and put the missfie count up on the screen of the liquid gauge and carried on home. I didnt get any more missfires and the car seemed to be running spoton so, not sure what it could be. Any advice is appreciated.

Pics look good, Richard 
Quick question, hope you don't mind? You changed your N75 recently, what sort of symptoms made you decide to try that? I'm finding power delivery feels a little lumpy, got a couple of flat spots which VAGCOM and rolling road traces don't show up anything in CFs or boost for. Also getting a strange fluttering noise on WOT in 4th from about 3k, 3.5k maybe. Any of this sound familiar?

Hi mate, if you look at my last rr day graph here, look at the boost. It jumps 3/4psi between 3500 and 4000 rpm, decided to change the N75 incase it was sticking. In regards to the flutter, yes I did get that with the DV30 fitted but it seems to have disappeared now with the 008 and the yellow spring.
Cheers mate. Sounds like maybe not the N75 in my case then, although I may change it anyway as the newer revision may behave better, thanks. As for the flutter, I have the 008 with yellow spring and it's happening now It's when on WOT, not on lift-off.
I'll see if undoing the N249 bypass helps. Thanks for your help as always

N75s aren't expensive so may be worth buying just to rule it out, I did change the N75 and the DV at the same time so 
you never know. Mine was exactly how you describe in 4th 3k/3.5k rpm.

Forgot to mention aswell, it looks like SEAT couldn't be bothered to do their job properly when replacing the pollen filter on its last service. After the 310 mile trip to Newcastle mostly being in the rain the passenger side floor is drenched. Just been out and refitted the cover for the filter

Have you rung them and had words mate?
No point mate, would fall on deaf ears. If I remember I may mention it next time the cars serviced.
