Just got back from doing another scan......
My injectors are maxing out.
Just did another scan.... they are maxing out at 22ms.
I ran into Raven (guy w/ the L67 Cavalier) after we did the scans.
He'* running a 3.0 pulley (I'm running a 3.2) and he'* just barely maxing out at 21ms, but his boost is 13psi. My boost peaks at 16psi.... which he thinks it REALLY weird for a 3.2 pulley, but the 16psi of boost does make sense that the injectors are maxed out.
Anyone got any ideas?
I don't have time now to post the full results of the scan, but I will tomorrow afternoon when I get back.

Exhaust Manifolds.... I have SLP Headers..... I thought they replaced the manifolds.
I've never heard of this "boost stacking".

Right. Forgot about your headers. DP is downpipe. That should have come with the SLP'*, so if your cat is new, and your muffler flows, rule out exhaust restriction as a KR contributor. Assuming KR is the problem, anyway.
SOMETHING is causing KR. I hate to throw this out, and you've heard it before, but that paint on your SC is costing you. Whether it'* the problem, or part of the problem will be hard to determine.
Anyway, you're boost stacking for some reason, and that'* usually an exhaust restriction.

If I've been boost stacking I've been doing it since the upgrades were done.
Ever since the new stuff was put on +13psi is easy to reach and in Performance Mode, 16psi can be reached at WOT on the highway (or 1/4 mile).
.... and yes the SLP headers came with a "down pipe"... I'm almost certain of that.... and I know I got a new cat from Intense when everything was installed.
..... so I don't know what could be causing this boost stacking.....
I don't think my exhaust could be the problem.... Rogue, Foghorn and Cam2k I believe are all using SLP (or TOG) headers and stock exhaust..... and they're all putting out more HP then me.

For one thing, I can go WOT from 0 or from 60 and the boost will still go upto 16psi, and peak.

But I don't think painting my SC has anything to do w/ it. I get the same results if I run her hot or cold.

Also.... how does one test for valve float....? I shouldn't have it because I have the LS6 springs installed.... should I?

No, I brought the paint up strictly as a possible KR contributor. Heat causes KR, and you want that sucker to cool off. Not sure how much of an effect it could be, but just something to throw out there. That paint isn't causing boost stacking.
I have valve float. It feels like your motor stops responding as you reach redline. Almost like a limiter, but it'* engine RPM related, rather than speed related. But remember that my 100# stock springs are 110k miles old. They're coming out this weekend.
I'd bet with LS6 springs, you don't have float. But you might want to re-torque them. What did you do with your pushrods, anything?
