I just got all the hoses ran for the Greddy Profec-B boost controller and when I'm on my low setting at 17psi I creep up to about 18psi but on my hi setting which I have at 21psi I can't get past 19.4.

Any idea why? My only thought is because I have about a mile of hose running around places, not really, but I have like 5 feet running from the wastegate to the valve body, and about 5 feet running from the intercooler pipes to the valve body. Then of course there is like 12 feet running from the fuel pressure line into the main unit in the cab.

Any other ideas if this one doesn't seem reasonable?
