mine is set to 15psi and thats what i keep it at. ive seen people run 20 psi after a tune and some mods. i have a b&m boost guage looks spot on to the B4 dash

Nice boost gauge. Very satisfying mod to do.

IMO, 20psi is way to much, and I would be concerned about that. My car boosts primary 14psi (0.8 bar) and secondary 16 (1.1 bar) but my car is a Japanese Legacy so has a slightly different setup. I believe 15psi is the norm for B4s. I was under the impression that a rise of 2psi from factory is safe but anymore may cause issues.

Agree to disagree. I saved myself a few hundred $$$ and am very happy. I love the mounting in the aircon thoug, looks awesome. I dont quite have the skills or time to fashion something like that.

And as for quality it is definitely reading 20psi. The car is tuned to run 16psi on both primary and secondary but i think the problem that im having is due to the small size of the wastegate. I have read a few posts around saying here that you get to a point when the wastegate is too small and cannot keep the pressure in the turbos down, and i think that is where im at now because im making close to 200atw. Luckily summer is on its way so she wont be boosting that high for much longer. But it only gets up above 16 on cold nights, and only above 18 when im driving hard on cold nights. Over 20 is a new personal best through the natio the other night but hopefully im not going to blow anything expensive.
