I run my Quadzilla StealthII on 90 hp and I have noticed a drop in PSI on the Boost gauge! Granted I dont focus on the gauge when I driving most of the time but it seems that I "lost" boost...? I hope this is not sounding ridiculous.
What are people running similar programs (around 90HP) pushing in terms of Boost PSI?! I am hitting 25
I have checked for kinks or leaks in the boost pressure line and I cannot find any (although I have not made a thorough investigation)

When i was running the 90hp tune i was seeing between 23&25 PSI so it sounds about right to me
