View Full Version : Tip Chip+ Valve Body v Tip Chip Only ????

I own an Audi RS6 and have been speaking with Vast performance about a custom program and was told that they have many cars Audis and Porsche that run faster times with just a tip program and that the cars actually went backwards when they had a tip chip and valve body upgrade.

Has anyone experienced this?
