New to the board & wanted to know if there were any flash tuner/programmers for a 2001 DTS? If so what is the one to get & what is the improvement in performance & fuel mileage.
Thanks!:D

In a word, no. What you see is what you get.

As Ranger posted: No. .........and the snake oil and air intakes don't work, either.

Spend the $$$$.$$ and install a CORSA cat-back exhaust. www.corsaperformance.com. There are no other aftermarket "upgrades" to the Northstar '00 - '04 drivetrain.

Spend some of your time searching around in the Seville, Deville, Northstar performance, and Tech Tips threads. There are a few small tricks which no one makes or sells but that you can do yourself.

Which is a bit better than 1HP per C.I.D. Nothing to sneeze at.

you can mod a Deville for over 600 HP!

realistically, give up, Corsa or a custom built knock off, thats as good as its gonna get

You got a tune on your PCM for a 2003? I'm still looking for something for my 99 :)
I might just buy a whole new ECU and redo the engine completely and run it off that .. Lots of fun :>

There's 2 sides to this story. But they're right, in a word NO. No mods, no tricks, just no.

Now if you're willing to be a tester there is one and only one person who has successfully tuned a N* PCM. He's here and his name is AJ.

Other than that you have the CAI from Volant and the Corsa exhaust. That's really it.

Thought so but figured I would check.Just a little hard when you get adjusted to 800rwhp & 100 psi boost to this.:histeric:
I like the car though & have a few boxes of turbos sitting around has my mind running.:devil:
Contact info on AJ would be appriciated!
The exhaust I already thought about doing a custom one front back but I like the stealth,but also thinking about stealth power.:cool:

YES:thumbsup:

I have been very busy. I have put so much off trying to get a new software suite going, but I have got no results on the new stuff.


I can set you up for no speed limiter and a mild boost in performance. A significant performance boost is what I am stalled out on.

I have not been over 80mph yet bur run her thru the first couple of gears.Did not want to scare the Frank Sanatra cassetts I found left in the glove box.:eek::histeric:

If you're going to NO squeeze a pre-'04 Northstar, please come back with your engine overhaul questions. It will keep us all entertained on those long rainy spring nights.................

The pre 04's are weaker?

The head gaskets on the pre-04's sit on precious little deck surface, and that is compromised by water passage castings very close to the siamesed iron cylinder liners. Doesn't leave much clamping surface, and the pre-'02 blocks had some casting difficulties which could result in coolant penetrating some cylinder head bolt holes and corroding the threads to the point that the head lifts. End result: excess compression or boost = blown head gaskets

LOTS of discussions in here and Seville/Deville forums for years.

Later design has a much more solid, beefier deck surface and different thread specs for the head bolts. Reported gasket failures are almost nonexistent.

Be careful !

late 03 also had a head bolt pitch change, my 03 has it, another reason why an 03 was the target STS for me

out of FWDs
a 95 is the best performer
then 93-94
then 97-99

I'll just let it roll then.Good info here!
On another note any one have the Gates water pump belt too long compaired to stock?
Pissed in my cheerios!:mad:

The long w/p belt is a new one. (This is beginning to sound like a broken record......), but try www.rockauto.com and drill down to your car and belts (3-rib). See who makes them. There are 3 manufacturers in there, I think. Heck, for $4.50 ea. get a couple.
