There is no GM stage 2 clutch so who ever told you this was giving you BS. If you really want to figure out your messed up idle then carb cleaner spray will do alot more than water as when you spray the bad line the idle/RPMS will jump cause it's letting in combustible gas where it should not if you have allready cleaned the TB/MAF. Does your so called custom tune allow for the the A/C idle drop and issues that are known for turning on the A/C and being on a stock or GMPP+ setup? And as far as a Factory boost gauge not reading good enough mine allways read right on.. Cold ventura nights netted me 17 PSI on GMS2 factory tune and i had to still had to have it re-flashed even once i was the first 07 GMPPS2 ion redline and just to get it to idle right as it was a known issue even on 42's.. Just saying..

Yeah I'm still on here quite frequently. And I'm not saying anyone on here is steering you wrong everyone has made valid points. I just came across this thread and wanted to give some extra info if I could. I have been a member on here for quite some time and everyone has been very helpful. It's a great forum to belong to. There is so much info that can be found here. And yes the car has always ran strong. No money was spared in making sure it was built properly.
With your mods at ZZP's shop should put you OVER 270.
I pulled 270 on ZZP's dyno and you have some stuff done to yours that I don't
When I pulled on ZZP's Dyno I had
So If you have a ported head and full exhaust, you should pull more then I did on the exact same dyno.
Also the 850 Idle is STOCK tune.
I have a Custom ZZP tune and my idle is 1000. Stays pretty regular unless I turn on the AC. When I'm moving, my car idles about 1200 rpm. Sometimes when the engine is cold while warming up the idle will be arround 1100 to 1200. If that's whats happening to yours you should be okay.
But I see in another post Tim set the idle high to help smoothen out the idle so I guess that's why.
