Has anyone seen or used one of these? I want a chip or ? but need some advice first. Fleabay Item # 7972957818
I have a 2002 A4 Avant Quattro.

 

I didnt look at what exactly the ebay posting is but as long as you stay under 16-18psi, which you wont be able to reach, youll be fine fueling wise. I have a boost controller set at a 13psi spike and itll hold 11psi with no limp or lean codes. the cars a little quicker, but not much. you need vag com and a boost gauge for sure before you do this.
