Sorry I missed your post from the other day....I haven't been able to check the board for the last day or so.....

So far as I've said, I had replaced the coolant sensor, and the MAF. I have the Revo 93 octane program. I have also turned the boost machine valves all the way off to take it out of the loop.

My problem seems to be caused by heat. I can drive the car pretty much indefinitely without getting on it hard and when I nail it, I'll get full boost to redline. But, if I keep getting on it, after about 6-7 times of full boost to redline, it the boost will drop to zero at 5k rpm.

Same thing if the car was started cold. The first few times I nail it, I get full boost to redline, but then, after a few times of that, the boost will drop to zero at 5k rpm.

So, after conferring with Schwing and MOBlueTT, it sounds like that the first few times is fine because the heat hasn't built up, but after a few times of full boost to redline, the heat has built up and something is cutting out the boost.

On Monday we're gonna VAG it and see if we can get to the bottom of this.

Best of luck..No upgraded FMIC? Could it be your radiator?

FMIC helped me a great deal with inconsistent boost.
