you need exhaust work, as is a plog and dowpipe or headers befor you can drop pulleys

I should be receiving my 08 pcm tomorrow afternoon, I'll check in after my first few runs with it... cant wait.

plog = power log

But in reality, you can get headers for > $200 and would benefit slightly.

And before you ask, they will fit.

vailskier3, what BCM issues are you having? Are you sure they're related to your 05 PCM?

i'm pretty sure they are because i can't use the 05 pcm's vin and it's causing issues. it could be something else, but i have lost my remote start (not a huge deal, but it'd be nice to have it back if i could), whenever i use the key to unlock the car (like when i drive somewhere and go for a run and take just the key with me) the alarm goes off.

those are pretty much the only issues i've had with it. oh, and i randomly get ses lights, but after i clear them, they don't come back...

here is the list that shows up:

[PCM] P2432 - Secondary Air Injection System Air Flow/Pressure Sensor Circuit Low (Pending) (Old) (History) (Current) (Immature)
[Unknown] B3948 - (History) (Current) (Immature)
[Unknown] B3949 - (History) (Current) (Immature)
[Restraints] B0092 - PPS passenger detection error (History) (Immature)
[Restraints] U1000 - Class 2 Communication Malfunction (History) (Immature)
[Restraints] U1016 - Loss of Class 2 Communication with VCM (History) (Immature)
[HUD] U1000 - Class 2 Communication Malfunction (History) (Current) (Immature)

Just wanted to update this thread with my own experience, as it may affect others.

I ordered my pcm from Will and, unfortunately the pcm would not even start the car. I spoke to Will about it and he did some research.

Although all pcms 2004-2007 are Delphi, some 2008's are Delphi and some 2008's are AC Delco. My stock pcm, unfortunately is AC Delco. According to what Will found, the AC Delcos, as of now, will not program and are different from the Delphi pcm's in some way that will not allow them to be interchangable. This means that cars with the AC Delco computer stock cannot be tuned as of now. Cars with a delphi pcm are fine, so check before you order, it will save a lot of headache. There is a label on the underside of the pcm that will say either AC Delco or Delphi.

As of now, Will is working on the problem to create a way of reading the AC Delco pcm and hopefully go on to be able to tune them and have them work in the cars. He didnt make any promises, however, he seems to be somewhat of a wonder with a tuner, so I personally have faith that SOMEDAY (hopefully soon!) my car will feel the power unleashed with an Overkill tune.

Now... Im gunna go sit in the corner and wait.. and maybe cry a little..

Guess i gotta check my pcm :*(

Oh no! Im an ac delco!

fixed

no thats what i have the L32 in the 07 an im orderin mine within 2 weeks

will im ordering my tune this week an was wondering if you can do a little tweaking to it.

is the new pcm unlocked?

Will's 06+ tune with the corrected fuel gauge is locked to protect his work.

Being that it seems he's the only one who's figured it out, that's understandable

i heard they were unlocked.
