I balanced the TB's on our Stelvio using a home made "manometer" fashioned out of two Starbucks Frappuccino bottles "burp". I used Marvel Mystery Oil as the fluid.. And using some simple instructions from "the net", I made the version that cannot suck the oil into the TBs.
As for the TPS reset, I believe I had the Guzzidiag software loaded and it was pretty straight forward..
