afternoon all

I recently had my car mapped to what the mapper classes as stage 3 but hardware wise it compares to stage 2 + with revo and apr. The map is from a local mapper so not from the big 2 mentioned.

The issue

I seem to have an issue when on WOT between 2500rpm - 4800rpm. The car seem to boost then flutters, i can hear what sounds like the dump valve opening and closing ( i have the forge atmospheric BOV), it feels like i also get loss of power between this rpm. Once i get to around 5k the car pulls very very well. I got VCDS today and used the measuring blocks that apr site recommends but this is where my knowledge ends. Could someone have a look and let me know what they think, is there anything obviously that stands out ? All runs where in 3rd...roads are wet so there is wheel spin.

I seem to have an issue when on WOT between 2500rpm - 4800rpm. The car seem to boost then flutters, i can hear what sounds like the dump valve opening and closing ( i have the forge atmospheric BOV), it feels like i also get loss of power between this rpm. Once i get to around 5k the car pulls very very well. I got VCDS today and used the measuring blocks that apr site recommends but this is where my knowledge ends. Could someone have a look and let me know what they think, is there anything obviously that stands out ? All runs where in 3rd...roads are wet so there is wheel spin.

Take it off and try again :rolleyes:

The best recirc valve for the TFSi is the SEAT (OEM) supplied Revision D valve which does not tear due to not using a diaphragm. The Forge Valve has been known to stick on a number of cars and offers no performance advantage whatsoever over the standard valve. They cost under £50 as memory serves. Best thing you could do is punt the Forge valve.

Trying to get your logs sorted on Excel to see whats happening under your bonnet oo :)

rev D now in it but the same issue. I dont think its happening as much but that could be the plezibo affect. I will need to drive it more and do more logs.

On the logging part what exactly should i be logging and looking for.

I had the same sound on my 57 plate cupra


It never used to do it and then all of a sudden started, no changes were made to the car so I don't know why it started.

is it usually when you floor it?

It's the exact same rev range as where I was having the problems. Booting it from 2500-5000 it made that noise and then it f**ked off, even if i didnt back off the throttle.

Yeah mate. If you floor it low down the rpm it flutters like crazy between 2500-5000. After that it pulls strong. If you floor it higher up the rev range it pulls fantastic.

Was reading a little on the logs and how to convert from mbar to bar. In some forums it mentions the k04 maxes out around 1.5 bar. There are some parts on the log where boost request is 2500mbar but actual boost is 26500mbar which I believe is around 1.6 bar.

Try a rev g valve mate, I had a rev d and did not like it and the car lagged power and felt slower, fitted a new g in and it's perfect now, was advised by a few on mk5gti to go back to running the G and I haven't had a problem since

Is the rev g not worse than rev d ?

I need to run some super unleaded through my car to see if the timing pulls back. But from my amateur eye the car looks to be boosting more than specified at the lower rpm. Could this be the cause for flutter, 2650mbar

It must have been the angle of the microphone on the lads phone

Mine was as loud as the one that you linked me to


Sounded like it had an induction kit lol.


I never found out what the problem was mate. It wound me up tho.

Lads, fluttering after changing intake is completely normal to some extend.
This is the way the ECU controls the boost, google flutter and stage 2+ do get some peace of mind.

^^^^^^
Agreed 100%. I didn't realise you were more concerned about the noise than the valve.
