I have a 2001 audi tt 225 6spd quattro
I am doing the diode mod
heres what i have ordered so far
4.3v 1w zenner diode
turboxs hpbc boost controller
boost/vacuum guage
How much will i be able to turn the boost up to? Will I need a 4bar fpr if so where do i get one?

 

The only other person ran it to 20psi and his a/f was 12-12.5:1 which is 100% safe and perfect for turbo cars trying to make the most power.

 

so i can run 20psi without changing the fpr? do i need any other gauges? i got this one http://www.boostcontroller.com/index...category%3D131
