    I'd say bit deeper but less burp on the upshifts/downshifts. Clearly louder/raspier when reved hard but still nothing annoying. Totally quite when cruising around. Wanted it to be tad louder tbh, it has sports cat not fan of a decat.

    New REVO fitted ages ago. Overall great experience, nice quality, progressive sound, good low end (better then any of the intakes I've fitted), noticed flutter noise between 3-4k revs, LTFT settled down at 9% which is ok and acceptable no throttle angle problems.

    Few pics:

    IMG_0314.jpg IMG_0313.jpg IMG_0317.jpg

    In regards to the flutter noise I get decided to do some logs and it comes up that fuel rail pressure drops between 3-4k revs which could be down to the fuel pump not being efficient enough so stage 2+ booked in for 19th:D. No problems when running low boost and timing or map is switched to standard settings.

    However just before I do that I decided to fit one of these bad boys and see if I notice any difference:

    Hope you like it!

    hi mate great mods, and pics.
    love the revo intake, and i'm also thinking to switch to that dv.
    when you'll fit hpfp be sure to get rs4 fpr as well as it makes a difference.

    Sorry to thread hi-jack Matthew. Just a note to readers of the forum, this problem was only an issue on one batch we had made. There was an issue with the second set of tooling that was made, we had a new tool made and all is now fine. Any that had issues were changed FOC.

    No worries Ben! Happy that you guys sorted it out, shame that I were unlucky to have one from the affected batch though as the intake itself was really good, well made and I did like it :(.

    Speak soon!

    this is what I'll probabably going to look into next however I suspect all this flutter is software related

    What sort of flutter are you hearing.....?


    Is it part throttle or on lift-off from full throttle,as what you're hearing could be surge related.

    My previous GT3071 did suffer from that,and would cause the boost to chatter a bit under some conditions.....the new one doesn't do this.

    I get fuel rail pressure drop between 3-4k when running aggressive settings thats when the flutter occurs and on the upshift when rev drops to around that region you can clearly feel lag in turbo spool. When running low boost and timing or standard settings all is fine and smooth

    If you don't already have an HPFP,the midrange pressure drop is down to the pump,and is because it can't supply sufficient fuel at that range.

    The RS4 fuel pressure regulator can help,but is most noticeable with a big turbo setup.

    Lower boost,or less aggressive settings will certainly reduce the fuel symptoms.

    This is why stage 2+ is on the way and booked in for 19th:D. Then if that wont help I'll do the rs4 regulator next

    I think you'll find it makes quite a difference,maybe not so much in top end power,but in midrange torque.

    The uprated pump really does fill out the area where torque drops off with the stock pump,but also after a few days running,the car will adapt and smooth it out some more.

    OK this is it! Finally managed to get up to stage2+! All thanks to AMD Essex who once again made my car even more crazy fast:D.

    Here is some examples why stage 2 sometimes suc ks and can cause disappointment:

    Stage 2 Fuel rail trims:

    Stock settings SPS Stage 2:

    Now after fitting LOBA fuel pump everything looks different and best of all car feels sooooo much better mid range, just wants to go! Shifts are crisp and sharp, even on D mode everything feels like there is more grunt. Great upgrade for every S3 owner.... Stage 3 next?:D

    Thats shows the problem very nicely.

    The Loba,Autotech and APR pumps all do much the same thing in terms of results,and certainly if I was buying an HPFP again,I'd go for the Loba right now.

    I can vouch also for the Autotech,which has been on mine for over 30 000 miles now,with no issues,but the proviso is it should only be installed by someone who can build it in a clean enviroment.
    Mine is running around 500bhp currently,with no signs of the fuelling running out,and the data suggest that mid-high 500s are OK with these pumps.

    The midrange difference with an uprated HPFP is very noticeable.

    How did your car do on the rollers?

    Any problems with the DSG or anything?

    Had a problem with the haldex pump and this made me take it off before taking the car to audi however now I consider to get something new.

    Got it fitted last Saturday and I'm extremely happy, Milltek was good but this one is just fantastic. Quality great, lighter and wonderful noise on upshifts. Not to mention OEM quite off boost. Exactly as I wanted it to be! More pics to follow soon

    Does look like a quality piece of kit, but I'm still intrigued by the valve tronic milltek unit connected into the canbus

    Ok first time during owning my car I managed to get such mpg-s. Its stage2+ with BCS, driving 60-70 steady relaxed driving, never before could've managed more than 32-33... Very pleased and that includes 20 min sitting in traffic too!

    Your right - reducing pressure behind the turbo creates greater kinetic energy at the crank - as the energy required to drive gasses through the choked D/P and cat are reduced.

    Bought myself another threat however there is a small problem

    2014-08-20 18.20.35.jpg 2014-08-20 18.20.41.jpg 2014-08-20 18.20.44.jpg 2014-08-20 18.20.52.jpg

    Dont know what to do shall I return it or just fit it as is. Its not cheap and I'm very picky with my car always want everything to be perfect. So in two minds however dont mind waiting a bit longer and get a replacement.

    Is that the Airtec from the group buy? Wouldn't stand for that, still 500 or 600 quid of your well earned!!
