    Get a FMIC aswell.
    Either go for a Forge 007 or if you want to spend a bit more then grab a Hyperboost Diverter valve. Leave Bailey alone...
    Get yourself a good Panel Filter ie Piper/ITG/K&N - Not a Induction Kit though, just panel.
    Make sure your Clutch/Flywheel are ok as you might end up renewing or even upgrading. Brakes you have sorted...
    With these upgrades Id be thinking of a Boost Guage, Nice subtle one to keep an eye on Boost. Also Id be upgrading the TIP to a Ally or Forge - You dont have to but ive seen a standard TIP with a 270BHP A4 (Nice car by the way Mark, if you are still floating about) and the Pipe was so weak and ended splitting.

    CLutch Flywheel aint a necessity but with these A4's after a good boost upgrade suffer from Slipping clutch, split pipes etc.
    Id also look into upgrading the N75 Valve for something more Viciuos BEFORE your remap.

    ....and last but not least How about unleashing some more power and torque with a Sports CAT, I have a Full miltek Turbo back and the low down torque and Grunt is a Beaut!!

    :respekt:Bloody 'ell, where you been hiding Jase?? Glad to see you still flying around in the Avant!!
    How is it these days, any changes??
    Thanks for the comments by the way, Miltek has made a massive difference, had a powerflow on the red one but too loud, these Milteks are spot on.Not too loud and the sports cat makes a massive difference, especially with Torque! I thought about the Blueflame and another brand (which I cant remember now) but just thought id go with the 'tek'...You liking my Otty Bumper, different eh! I got it of a guy on here after I was trying to source one for months but Shipping was a killer then just by chance he was selling his.

    aye mate still got the avant and finally sorted the hanging revs issue with a clutch switch and a bosch maf, appart from that its the same. i was after an oet bumper but couldnt get one for less than a grand so opted for the reiger
