[s-cars] Stock boost levels?

[James Shackelford]

I just got around to installing a boost gauge and was wondering about stock
boost levels.  I have only had the car 4 months, the previous owner bought
it from a friend in Vail who was an enthusiast and had two UrS4s.  I have no
idea of what was done to it.  It has Eibach/Bilstien suspension.  The
Michelin man hose was replaced with a Samco.  If I recall, stock boost
should max out to about 16~17?  Is that right?

 

On the freeway, 5th gear WOT, it boost to 22 and then settles around 20-21,
with no surging, same in 4th.  Could it be chipped?  I will pull the ECU and
take a look at the chips next week.  Wastegate was cranked in, but I
loosened it all the way flush because of surging.  Boost is very smooth now.

 

Thanks for the input.
