GMPP should sell tunes.

There is not much horsepower added with a manufacture's tune. That's why they can offer a warranty. It's usually a very safe and generic tune. In my experience, the great advantage in these tunes are the improvement in throttle response and increase in power near the red line where as normally the power is being pulled in anticipation of the limiter. The open air filter adds some noise too which adds to the excitment. If you track your car, you never miss tha downshift blip as it is always there unlike the standard set-up.

So yes I think its a good deal if they offered a CAI/tune under $1000.
However an after market system will give you a slightly better tune and can be removed easily for warranty work which is what I do with my Steeda CAI/tune.

I think a GM tune would be awesome.

Want AFM on or off?
Want more HP or better Gas Mileage?
Want shift points changed? (which I don't see how this could hurt the transmission in any way whatsoever)
Want a tune for your added CAI to take full advantage of air flow?
Want a tune to support the new headers exhaust you put on?

These aren't complicated tunes, they won't hurt the drivetrain in my opinion - the car can take added power from a CAI and exhaust, and definitely can handle AFM being turned off on automatics, and the HP gain which would reduce gas mileage cannot stress parts that much.

Torque management may be an issue.
Faster shifts may be an issue.
Oh - the tap shift thing - yea, that should be a lot quicker, I hate the delay

harley davidson does this .
but even they as of late have offered less full performance
tunes and more "street leagl" tunes.
but they work real good when only a free flowing air cleaner and free flowing exhaust is installed.often known as a stage one kit.
my self this would be great gmpp a, cai,cat back exhaust,and tune that will still enabe me to get past the inspection a/f test required once a year here in ny.and pick up a little more power and good sound...

Just have GM max tune it from the start...why should we pay more? That would only encourage car companies to "undertune" cars and find a new revenue source at our expense. Imagine if the new Camaro V8 was 355 HP, many would still have bought this hot car and unlikely Chevy would have sold it for any less money $$$...

Now GM decides to charge for a tune that makes 400HP and has you paying $1500 extra? Bad idea for us all.

Just move closer to me or cover my fuel cost and overnight stay to come to you. Problem solved!

See my signature for tuning rates.

GM gives you their approved tune right from the factory.

A tune is simply an aftermarket reprogramming of the computer.

You can buy a Diablo or HP tuner program, and adjust each parameter yourself.

GM has the computer flash programmed exactly how they want it.

If they find a better way, (as far as they are concerned) they will issue new programming. (reflash)

It is designed for many purposes: Performance, emissions, driveline durability, etc.

When a car is tuned, or reprogrammed, it is violating GM's design, and therefore voids the warranty, if they want to.

There will never be a GMPP tune. It would be like the police selling burglar tools.

I heard rumor that GM may be offering a performance tune for the SS

[RickRay]

A tune would be great..just as long they can tune it so that it doesn't burn Rich...I'm tired of always cleaning my Exhaust TIPS.

[PieNsky]

Yeah, the V6 really does get them dirty.

I can give you an example. From 2001 to 2005 I was part of a company that had a network of 80 GM dealers that installed our supercharger systems at the dealer level. I did all of the engine and transmission calibrations and install training. They were all on GMC, Cadillac & Chevy trucks and SUV's. During that time frame there were 400 systems installed.

These were all installed on brand new vehicles. To date there has yet to be a powertrain failure caused by the supercharger system. Many of these vehicles have well over 100,000 miles on them at this point. The system added 90-110 HP depending on the vehicle.

Just my 2 cents.

Yeah it would be cool to have them make tune adjustments for LT's and CAI's. My understanding is the blue oval will offer you a tune for the stang.

Volvo sells them. My buddy had the dealer apply a factory tune for $600. It gave him something like 35 extra horesepower. Warranty still intact.
