Turbo or Supercharger
So, while I understand that obscene HP is terrible in a FWD and that it will cost this and that, my question is pretty basic.
Is the EFI tuning capable of dealing with a built Northstar, now? I know it wasn't 00-05. But for 06-12, am I to understand that technically, now, one could turbo or supercharge or just all-motor it, and be able to tune it appropriately?

Re: Turbo or Supercharger
Nothing wrong with more horsepower - but the 2000 - 2004 PCMs haven't been tuned yet. Many of us would like to get a pony or two more.
As far as 2005 and later PCM work, ask Wester's Garage in Canada. Some members, somewhere in this forum, have had tunes done but I have no idea if anything worthwhile was accomplished. There's another group that claims to tune PCMs - you see them referred to once in a while, but apparently some of their claims are just that: claims.
A basic problem with forced induction in any of the FWD series is "Where do you put it ?".

06 pcms aren't either. 07+ only unless you contact madtuner.

LATE 06 got the 07 ECM and can be tuned. The 05-06 cannot.

Re: Turbo or Supercharger
Well, I am refering to the 06 and up DTS. It was Jim's tuning from Blackbear that got me to wondering. And if its a fully tunable computer, then that should mean that I could turbo it. It shouldn't really hurt any of the actual engine or transmission components at a low psi. Of course once you turned up the psi you have to start building the engine and tranny.
If the transmission can be tuned as well, it may even be possible to actually use some of the power off the line. Certainly I could have the top speed limit removed and increase 0-100 times.
I don't even know if I'll be getting a DTS (I want to but finding one with all the features I want isn't super easy) and I certainly don't know if I'll be trying to stick a turbo on it, but I was certainly curious.
If I end up getting a DTS I'll at least mock up some piping to see where a turbo could be shoehorned.
