Nice setup...I did the something similar on my Vortech out of an injen intake...
Out of curiousity have had the car re-dynoed? I ask because when I installed my intake on my car my car definitely ran cooler but I noticed it ran a little richer too...when I took it in to re-dyno with the new intake I lost 2 psi (keep in mind my modified setup runs 17.5 psi)...the boost curve was exactly the same until around 11~12 psi then when slightly down from there to about 15 psi max...
Maybe the intake only affects higher than 12 psi setups, as most Vortech and HKS supercharger setups run up to 8~10psi...

^^ You may have lost power due to the inconsistency of the intake pipe.
But you have raised a valid question. The extended length of the intake pipe can possibly decrease the acceleration or 'vortex' effect of the air velocity causing the loss of power. This is a completely hypothetical assumption from a novice though... thoughts?

Well Berk came through form on some New HFC's. I should have them by Friday. I have also been logging some data with Cipher.
I have had this on going issue with the idle and Hot starting. I am seeing that my A/F Correction Factors are all over the place at times. The A/F Correction Factors should be close to 100.00% (+/- 10%). Mine are going above 125% and below 75% at times. Now when I first start the car from a cold start I am at the 100% mark. But once it gets hot it's all over the place.
So till I can get the car out to UpRev I am going back to my GTM Base ROM and OEM MAF. This will keep things safe for the time being.

I am thinking it has to do with injector scaling and the PMAS. It's never really been right since day one.

Was driving the car home, and the car got real loud all of the sudden, lower pitch and louder/big time drone in cabin. Car feels a little slugglish. no cels, oil pressure, fuel pressure, temps ok. I did notice that before this, the exhaust note would kind of "gurgle" occasionaly when decelerating.
Could this be an exhaust leak (blown header/cat/exhaust gasket) or a clogged/collapsed cat(s)? Any other possibilities?
After I noticed the louder/deeper/crappier sound and drone, I did not push the car, but I did notice that reported boost was lower than when the car sounded normal. I thought that if a cat collapsed, then backpressure would increase and psi would increase on a supercharged setup? Maybe I am wrong in thinking this? I guess the mettalic core could have gotten blown out and stuck somewhere in the exhaust? That would really suck, but I have no idea since it's night and I can't get under the car.
Hopefully I can get it to the shop/on a rack sometime soon. I'm not going to drive it until then, but the shop is ~28 miles/40 minutes away. Ok to drive it there like this?
Any ideas on what happened?
Im sick of pouring more money into this. I'm close to calling it quits, parting out, selling the car, and moving on to another platform where it will stay stock.

Sorry to hear your troubles... You do have alternatives.... I thought about stock block FI, or built motor + FI, but after years of research, and experiences. I have decided to stay N/A but with 2 more cylinders...
You could always run a V8 of the LS type. Just a thought.

Jonny it definitely sounds like a leak of some sort, the only question is where. I don't think its a cat problem.
Given that its most likely a leak, you'll be ok to drive it to your workshop.

yea, tech diagnosed the exhaust gasket blew out (between amuse b pipe and muffler). A new vibrant gasket was ordered.
cdox--I'm actually about to do the same thing. I'm deciding between just taking the supercharger off and keeping on the bolt ons and keeping the car for awhile. Or converting everything back to stock, parting out and selling the car stock (I think I might have a hard time selling the car as is for the price I would want). I want to move on to a different platform...So quite possibly there will be many jdm parts for sale (Arc radiatior, Arc catch can, Arc oil pan, Endless full 6/4 BBK, Amuse exhaust, vpro, etc.)
How hard was it to put the fuel system back to stock? Are you keeping the Z or selling it?
