Spot on El!
So today I fitted the N75 valve which I ordered earlier in the week, this i the 'E' version, my old one that came off was an 'F and OMG it is unreal. Night and day difference!
Improvements:
- Flutter noise in 4th, 5th and 6th under WOT has completely gone! Car just keeps sucking in air and goes like a bullet train!
- No more boost spiking past 1.5 bar! It now holds strong in every gear at 1.5 bar. Seriously loving this fix!
- MPG seems better? I went on a test run after I fitted the valve and it would usually use another 10 miles or so of fuel on the exact same run I seem to do each time, and well, it 100% is using less...
- My exhaust seems louder! Maybe now the boost is running back as it should? Seems much louder even just blipping the throttle when I got back it is definitely louder than before.
- More responsive. Without doubt, this has reduced low down lag massively. Night and day. It's got the lower grunt now. I noticed just where I wouldn't need to change down earlier as before I would think 'ok I'll drop it into 3rd here to keep the revs up'
Overall, stupidly happy with the new N75. The car is back boosting to it's best, and it just makes me realize how bad the old N75 valve must have been. Going round my mates in half hour or so, so have another chance to test it out
p.s I hate the original clips that SEAT used on the 2 pipes running off the N75! The metal one below being the worst.. I replaced them with a 8-11mm jubilee clip and a cable tie! No movement after the test run so all is secure.

I also posted off my old TX Autosport FMIC today to its new home.
