Ive done about 31psi once,not intended.

 

stock boost is most definitely about .6 bar. The reason I know that is because I can't get my boost controller to change it....lol.....it sucks, especially on the 28r.

 

They can handle up to 20 roughly psi? My 97 a4 1.8t was hesitating under full throttle, producing 20-22 psi cause there was too much air in the cylinders. Simply not enough fuel.

 

So if stock is 10psi and my boost gauge is peaking at 7 could that be because of my after market FMIC? Or am I leaking boost somewhere

 

My apologies, I read the b6 stock psi. Looks like everything is good

 

i am trying to run like 16 psi with a boost controller but feel like im getting fuel cutout after 14 psi is it fuel cutout or could there be another problem mabe a boost leak any help would be appreciated thanks

 

This is really bad idea. You're relying on reactionary fueling, where you'll run lean until the O2 sensor tells the ECU to increase fuel. Get a chip and go with that so you can run higher boost safely and with proper fuel and timing control.
