Hey guys just picked up a 99 a4 b5 Quattro 1.8 5 speed. It has a k&n intake. A full 3inch exhaust. Havent checked for a dp yet. Stock ko3 turbo and a GIAC stage 1. My question is how do I know the tune is a solid stage 1 and ik getting the max power out of it? I'm pushing 10lbs in 1st 2nd and between 3rd 4th and 5th its at 15. Any info will help thanks!

 

Bump any help?

 

Mike or any high rep audi owners help a guy out?

 

Well... I run a N/A B5 so im pretty clueless, but maybe an electronic boost controller will steady the boost output?

 

I also run the Giac tune, its one of the best you can buy for a stock k03. However I'm pushing between 12-14psi in 1st/2nd and 16-19psi in the rest; but I do have a few other mods. As far as the boost controller goes...you don't need one, at all. And you should change over to a 710n diverter valve btw
