wondering if this is true or not
Well from what I hear. Whatever you put on this car like full bolt-on's the ECU will still make the car run at 260hp. So if you plan on doing anything to the car you really can't because of this.That is the stupidest thing GM does was dumb crap why would you make a ECU do that if you are putting out a tuner car? Really don't make no sense what so ever. So there is no point of even buying this car if you plan to Mod it. Its just a waste of money. So this car is pretty much stock even if you but full bolt-on's on it will still only make 260? That's because of the ECU and you can't buy anything to crack that and GM is not going to sell a ECU where you can mod it. This is a joke. How do I contact the GM performance division?
is this true, this is from an old thread and i also saw it in the GM stage kit thread too, and isn't the new GM stage kit releasing this function so you can keep your tuned HP?

it's called TQ on demand.. yes the ECU will keep the car's TQ right at 260.. on a stock tune.. but the stage kit raises the hp and TQ and keep's it there.. once tuned the car make more than 260 tq.. IIRC it break's the 300 mark.. so how would it still be stuck if the computer is limited 260 once it's tuned.. i believe he is talkin bout a stock tune..

yeah but won't it take this function away so you can have more than the stage kit torque. Say i have full bolt-ons and the gm stage kit, is it still going to retain me at the stage kit numbers with the bolt-ons or can i keep my HP like every other car?

On the solstice forum there is a guy that has the stage kit on his Sky and he also apparently works close with the GM performance division. He has stated that with the new stage kit it will allow new bolt-ons to make more power and stay that way. So if you're making 290hp with the GM tune then bolt on a CAI, DP, cat-back, ect. and end up making 310hp it will remain at 310hp. But this is just hear say.

Apparently from talking with my friend last night (which has stayed on top of this since the get go) they have released the GM Stage Kit for the Solstice, Sky, HHR SS but not for the Cobalt SS yet. I've heard rumors of there being a CAI included with our kit, which might be why ours hasn't come out yet. Down side to it is that I've also heard our kit will sale for around $800 with the CAI. But like I said in the other post, this is just hear say.

i had a boost controller lying around and put it on to see what it would do and first pull 20 psi was like DAMN! spinnin it everywhere, and the second pull backed it off to like 13psi via throttle plate and butt fucked it. ran like it had a anchor on it, took it off and and left it stock until tuning.

so im guessing that the stage kit will release the ECU of its function of only keeping 260 TQ and allowing you to keep you modded TQ level. So if you have the stage kit and full bolt ons you will keep the torque of the stage kit and full bolt-ons like a normal car????

they are still limiting torque, thus why the solstice MT is @ 330-340 ftlb and the HHR is is @ 315 ftlb

The guy in the solstice thread did a good write up on how this works.
The stock ECU will keep the car running at 260 torque. (HP is a function of torque, limited to this torque level the car puts out 260hp)
However with the GM tune apparently the "tune down" feature that keeps the car at 260 torque when you add bolt ons, is released.
So the ECU will take advantage of any increased air flow you can give it, and run at the optimal level.

ive been talking to pyskosteve (******* smart dude) and he said that GM will release a lower TQ and HP tune but take off the TQ management. He also said that those of you that are untuned and have Exhaust and other upgrades, your TQ is still stock amount until you become 100% tuned (GM or pyskostevo etcc......).
Doing any power mod without a tune, (GM or otherwise) is essentially useless on this car

quite honestly i think everyone should go with a pyskostevo tune if their not worried about warranty. He is probably one of the most knowledgeble tuners for the LNF possible. He does extensive testing. His **** is crazy!!!!
