Figured it out! The starter seized over the winter sitting. Perhaps moisture and cold temps did it in. I got it to break free but it intermitantly works so time for a new one. After about a min of runnig my car it starts to smoke... Doesn't really smell like coolant though. Shut it down check everything, seems good. Pull my car out of the shop and the thing is smoking pretty good. First thoughts are FML head gasket??? How??? Talk to Taylor (Infraredline) as I'm looking at my car ready to cry and he says, you blew a sleeve right? Know where all that coolant and oil went? Exhaust. Brian a turbo LSJ he was about to start tuning blew a sleeve and he said after they got it going it smoked hard for a few hours lol. I didn't even think of that! Went to start the car to go drive it and no start. Fakin starter. Sure sounds good though!
New starter asap and break this thing in!

I bought a phenolic spacer for my SC build, but didn't end up using it, because I didn't have the proper bolts. But ive the same issue that you're talking about. Whenever let off the gas, or idle, the temps slowly creep up. as soon as I get going again, they rapidly drop back to a stable temp.
Heres one theory on what I think is going on:
(I'm not an expert, so dont freak out on me)
The reduced airflow, both through the intercooler and through the manifold, is allowing more engine heat to warm up the manifold, including the laminova cores. so when the throttle body is shut, there isnt any air to take away the heat, so your IAT's rise.
To support this, I notice after driving, i shut off my car and feel the surface of the manifold. it usually feels the same temperature of the ambient air. But if i come back in half an hour, it feels much hotter.
Now, the phenolic spacer does not eliminate heat transfer, but slows it down. the heat from the engine does not instantly warm up the manifold. I think many guys got rid of their phenolic spacer because they were expecting lower cruising temps, or peak temps. It seems to work best to combat heat soak when your intercooling cant work as well, due to a closed throttle body, or being parked.
Is this rational? Let me know if I am missing something here.

Heat soak occurs when a component reaches temperature equilibrium with the gasses flowing through it. In the case of an intercooler, this is a bad thing, and the efficiency of the intercooler drops significantly.

Lol ya I may have to do that. Pretty hard to clean out though when my catback is one solid piece. Taylor said Brian's smoked for a few hours after they got it running lol. Don't need people pointing and laughing at my choo choo train Balt lol

So I got my starter issue fixed. Was just a corroded connection. Go and take my car for a rip to do some heat cycles and break it in a bit. So after a few heat cycles I put my foot into it a bit. This thing is making almost 30 psi! I was making like 27 last year at redline! And I havent even pushed the car close to redline yet. Wtf...

Well I'm a little scared seeing my 30psi gauge almost bury out and I haven't even put my ATI damper on yet lol. As for power I didn't really play much, my option b wasn't self bleeding for some reason and my IATs were like 140 cruising so I didn't push it.

Ya I haven't really dove that far into it yet. Unless there's a piece of sleeve jammed in my exhaust I don't know what would be blocking it lol. I'm catless so it wouldn't be a clogged cat.
you do realize that your not going to get a big fat ******* huge piece of muffler clogging metal through 2 tiny ass valves

the stock cams are on a 107 lsa(a lot of overlap) which blows a lot of cylinder pressure off at low rpm and builds it at high
the zzp stg2 cams are on a 111lsa(less overlap) which blows of cylinder pressure at high rpm builds cylinder pressure at low
now the cam timing differences stock cams and the zzp cams would be building more manifold pressure due to the longer period of time that the intake valves are closed before opening since that is the case then a 2.7 pulley would be building pressure equivalent of a 2.5 or smaller the less the over lap the more cylinder pressure hence the more manifold pressure its cool how valve timing can affect things
even on the stock muff i didn't see what i am(stock cams) with the zzp stg2 cams and i am also on a full 3in exh

iirc blue you have the zzp whisper res? those things have been popping like rpt motors lately. i wouldn't be suprised one bit if part of it came loose and was partially blocking it off.
