Y Pipe Eliminator: Right before the throttle body on the GLI/GTI is a Y pipe that leads to a resonator. It goes to left side of the engine cover and people mistake it for a coolant line. It's just that, a noise maker that the turbo has to fill up with boost! How can we get around it? Use a pipe from an A3 and delete this performance robbing noise maker!

This is the straight intake pipe that can be put into place of the Y pipe.
Descreening the MAF can be done on various cars. The best way to see if you can do it on a MKV is to log intake values using a vag-com.
Once you get the intake/engine cover off, the maf screen just pops right out. Worth a few extra hp? If you have the time, you may want to try!
Reset fuel trims: If you have a vag-com, reset codes, even if you don't have them. Fuel trims will baseline and you can start over. This could mean several extra hp for a dyno day. Or you could lose several hp for a dyno day ;). You'll need to experiment for the best results!
