    Fair comment, but at least unlike some kits they have given consideration to the MAF sensor pipework diameter. Another forum member on another site I frequent has had so many issues with his Dbilas he's removed it and gone back to stock airbox and Carbonia intake. The foam they use forms a seal against the bonnet lid, is fireproof/heat resistant, and should you run out of air in the filter enclosure space means you can keep pulling (albeit warmer) air from the engine bay.

    It's not going to be everyones bag, but I''m happy buying from a company that are entrusted to make filters for £1m rally/race cars. Horses for courses I suppose.

    warren, I have been in touch with Andy and I am pretty certain that I will go for the ITG.

    However, have you experienced any issues with the kit? I can understand if there are any initial teething problems with new kit but have you noticed any or had such issues?

    Nothing that I've noted. All positive so far.

    There are issues I've had which were there before and after the CAI, but they have not changed.

    1) Boost modulation flutter under full load
    2) Slightly rough idle

    The second issue has been slightly improved by a track day and the catch can, and the first issue seems to be lessening as the weather gets colder. However I tend to bit a bit paranoid about noises / inconsistent idles etc.... so it may be nothing. Ten years ago if you were running well over 300bhp out of a 2.0 litre you'd be happy if it idled inconsistently if at all!

    cheers warren for that - you have the latest Audi DV installed don't you?

    Is there any noticeable difference between that and the standard one? what about comparison to forge?

    thanks

    I get the boost modulation, had it before and after the intake was fitted. I've spoken to Revo about it and they say it is normal, but I'm going to do some logs this weekend to make sure all is well:icon_thumright:

    I had a very early Forge DV, but was finding that the car was slightly jerky around the point where the DV cracks open. Even after it was serviced (the DV), it didn't feel it was any better, so I decided to try alternative solutions.

    I had an original early style DV which I put back on, but it didn't seem to be coping well with holding max boost at Revo Stg2+, so as a purely experimental exercise I changed it for an OEM rev. D unit. Whilst much improved over the original OEM unit, I'm still not sure it's consistently holding the max boost as well as I'd like (purely from gut feel, not logged).

    There are now 3 options:

    1) Leave it and accept it
    2) Go back for a Forge with a new yellow spring
    3) Buy a Turbosmart DV

    Until I've done some logging of the boost I'm not going to change anything, but given where the car was in terms of general performance it's league ahead. The cooler spark plugs seemed to have given it more consistency, but then the air temp has dropped significantly recently which helps these cars no end.

    I used to get the flutter with my Stage 2+ but the yellow Forge spring plus the Iridium plugs appears to have cured it. Although as Warren says it could be that the change in temp has had an effect too. The total cost of the plugs and the yellow spring is under £40 though so well worth it anyway even if it only incrementally helps the situation.

    Very interested in this 'Boost modulation flutter' you are talking about. I now seem to be getting this on my TT-S after a stage 1 remap. The best way of describing it is that when opening the throttle fully in 2nd or 3rd gear I can feel and hear the turbo come on very strong but then the boost seems to drop and I can hear a sort of on/off whooshing noise from the turbo. Is this what you guys are talking about?

    I'm also running the latest OEM DV.

    Very interested in this ITG CAI by the way, probably going to be my next mod if its available for the TT-S.

    Sounds the same, but having spoken to Kev at Revo it's actually not a bad thing. It's basically the cars ECU managing the tolerances, and the losses are managed, not detrimental.

    As for the ITG, not sure they have done one for the TT-S yet, but given your battery is in the boot you may have more scope than in the S3.
