Actually, the third progression hole will go a long way to helping you to correcting a bad transition phase. The VW people have known this trick for years. If you trouble is transition, try drilling out the third hole. It will save you a lot of time and money---and frustration. If you problems are other than transition, the third hole is not the answer.

Webers are a great system, but....bubbagump does have a point.
