GMPP should sell tunes.

I have checked around and see that tunes run around 600.00 or so. And of coarse we have no drivetrain warranty if we do them. BUT what if GM would come out with some good tunes that are comparable to what you get from tune shops and charged say 1000.00 to 1500.00 for them. And you get the to keep the full factory warranty. Would you buy them?

I am just thinking if we could show GM that there is enough interest in them they may make them. The extra money for tune is there to cover something if it does break during the warranty. I just really think the L99 so much more than the LS3 has been nannied to much and GM selling a tune would rock.

What do you guys think?

Never happen. They cannot alter anything that enable them to acheive their MPG & durability ratings.

Or...they could endorse some of the reputable tuners for a percentage of what they charge for the tune and not void the warrany if one used these "select" tuners......pretty much pure profit, win-win for all!!! Use their knowledge & experience for GM's (and the consumer's) benefit.

MPG ratings would before any tuned installed and as far as durability, I would
bet the tunes would have little to no impact on it. Only time I've seen a problem with a tune is when some knucklehead doesn't know what they are doing. To answer the OP question, no I would not buy a tune for $1500, maybe at $1000, but I better have lifetime tweaks available if I need them.

I would think they would be fair in pricing at $1500 as it would allow them to add in additional insurance for breakage that is going to occur. Higher HP = more breakage...that's statistics speaking not whether you consider a tune damaging or not. If GM were to continue powertrain coverage with a tune, they would have to charge more than your streetcorner tuner as they have to cover breakage that the streetcorner guys doesn't.

As far as GM "getting in bed" with select tuners...I don't know if this would work as those tuners would have to have their hands tied as far as "custom" work on covered vehicles...or have GM approved and GM disapproved tunes for sale.

Again gm already sold injectors/ pulley upgrade for the S/C cobalt with a tune.

If GM sold a tune only for the Camaro for $1500 and people bought it, they should be killed. Both GM for selling it at that price and the dummy who pays $1500 for a generic tune.

HP gains from a tune on a stock Camaro are not enough to overwhelm the
drivetrain in my opinion. I just have not seen that much gain with a tune alone. Now you add that with other go fast goodies then yes the weakest
link is more likely to be exposed, but just getting your car tuned to be as efficent as possible is not going to be a problem. In fact a tune, CAI and exhaust in my opinion will not test the cars limit.

I agree they should sell tunes and I don't even have my car yet! This would be an easy way for GM to pull in some extra revenue and the dealerships already have the necessary equipment on hand. I'd pay $25 - $30 per rear wheel pony with a non-voided warranty.

the sky too, I forgot about that one. Basicly Im saying GM can and has done it. It just appears they wont for the Camaro. Theres more money to be made in voiding warranties than cpu upgrades.

Man I wish MPG would be an issue because the car only has to meet thos standards when new. Once its purchased all bets are off.

So, adding horsepower does not add stress? You might not see the HP from a tune breaking something immediately, but the added HP could shorten the life of pieces of the puzzle and cause added warranty claims.

Of course adding hp adds stress. All I'm saying is these cars are not maxed out on what they can handle from the factory. I'm sure someone with more knowledge than I can chime in here and give some specifics on how much the stock parts can take.

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.

Cheers.

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.

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 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.
