    b8 2.0tfsi revo stage 2 340ish hp but when i put down the gas an change up a gear there is a small delay like the boost has droped of an needs to spool up again so i lose a litte bit of performance for a split second, if i drive 90 percent the car is fine but 100 percent a small delay might be the diverter valve leaking a little ,would a blow off valve help as it gets rid of the built up presure so the turbo can spool faster anyone,,,

    Because of the higher boost levels, its need extra time to reach the higher levels. When you close the throttle it will dump the boost and just needs a bit longer to spool up again as its working twice as hard. It wasn't made to run at these levels.

    Best way to get it right is to fit a bigger turbo which uses less boost or/and a tubular manifold which helps the turbo spool quicker to make the power or live with it.

    Looking at the standard boost and revo boost levels, its twice what Audi ask of it. Your turbo is on its limit really.
