The best I ever saw, when stock, was 19 psi's. That took a hard romp in 5th gear, starting at about 1500 rpm's.

With only the BHAF and 4" exhaust, I'll make 20 psi.



Add the Edge EZ and boost elbow and it will hit 31 psi.

i had the same numbers that you are coming up with. i found out the gauge i had gotten was 4 psi off, and it was brand new. what brand did you get. i got isspro

I also could not get above 19 psi before I disabled the wastegate (seeing about 30 psi now).



Is it possible you crushed the compression sleeve on one side or the other by overtightening the compression nuts? If the sleeve gets cockeyed while you're tightening the nut you may have slightly crimped the line?

Stock with K&N = 21lbs.

Ez, boost elbow, 275's with K&N = 34lbs so far.



I haven't kept the engine at WOT very long but I have no problem shooting through 30lbs running empty on small hills if I step on it. (if my gauge is accurate)

 

[THancock]

Mine dead stock 20lbs. Now with EZ and elbow 28lbs.

 

[RJOL]

Total stock = 18psi... . With EZ and boost elbow 26psi...

Stock - 22 PSIG



Now (see signature) - 32 PSIG



Both of these are most frequently seen when towing our 36' 5th wheel.
