    ahem.......what exactly did you expect?
    If you wound it up high enough your injectors will probably have been close to running out of steam.
    seriously high EGT, detonation, wounded rods and piston crowns

    is the manifold glowing at all, this would suggest definitly high EGT. though even driven hard it may glow a little anyway, mine on 1 bar boost glows very orange.

    if just turbo then maybe the oil supply is not good or turbo is worn.

    just a guess.

    You turned up the boost, but by not increasing the fuel supply either through longer injector pulse widths or by using larger injectors (if the stock ones are being ran at over 90% duty cycle. The chip would compensate the rise in boost with a rise in injector pulse width as well as the rise in fuel pressure from the fuel pressure regulator.

    I was gonna say there are two things that will make a turbo get that hot. 1: you are running out of fuel causing a lean condition. You have heard the saying lean is mean? Well the extra fuel not only richens the mixture, it also cools the cylinder slightly so you'd have lower exhaust gas temperatures which are fed directly into the turbo. 2: the turbo is oil cooled so if everything else was fine I'd suspect the oil line is plugged up.

    Luckily you didn't damage the motor from leaning it out that much, you could have had detonation which if you're lucky would just pop your head gasket(s) and if you're unlucky, maybe bend a rod, burn a hole in a piston or crack a piston.

    Anyhow there's a reason why these cars need a chip and not just a cheap manual boost valve. I'm sure you can get away with upping the boost a few PSI with an mbc but at some point the computer won't add enough fuel because it's not in the factory programming to see that much boost. Also I've heard more boost without a chip can cause the computer to cut throttle and you'll lose performance which sounds like what it did to you.

    Good luck with the chip, they work well and offer more power and retain factory drivability. Now work on your exhaust or fit some bigger turbos in the car!!

    Put aside money and save up for a proper chip from one of the well known tuners such as MTM, APR, GIAC, Dahlback, or Vast. I wouldn't trust some off brand chip to work properly in my car and I wouldn't want to have to pay to buy a new engine when you blow it up with a crap chip. Those companies listed have done extensive testing and tuning for the Audi cars. Now if you are buying a used brand name chip and you find it listed on ebay, well as long as it matches your ECU model, go ahead and save money that way. But stick to name brands or you never know what you might get.
