Will GM release an ECU upgrade to boost horsepower considerably?

The rumor mill says that GM will release an "upgrade" shortly after the Cobalt SS hits the streets in large numbers that will significantly increase the stock horsepower output.

Some are claiming a 35hp to 70hp increase (mostly achieved by raising the boost)

What does everyone else think?

I highly doubt that GM will release a 275HP Cobalt, mainly as with its low weight it would come to close to their other performance cars, not to mention cross segments with other cars, I.E. the GTP G6, and SS Monte Carlo.

I think what he means is a package close to what dodge is doing with their SRT4. Add on the power after the purchase.

It's going to be nice if they raise the rev limiter.

I think it's possible, I work at a pontiac dealership and we have no such info yet, but if they do it would be interesting to see what kind of numbers it could put down.

Yah, I was referring to an aftermarket package, ala Stage 1, Stage 2, Stage 3, etc.

Ohh, well that seems much more likely, but then its up to dealers or not whether to carry them. GM might do this as they did it with the GTO's sport appearance package that was going to be a factory option. Havn't herd anything about that though.

Well as far as an aftermarket packakge I can honestly see somebody doing a BPU (basic performance upgrade) which have become so popular now adays which seems like it first started with the supra guys so you might have a BPU car with a chip and a BPU+ would be lets say a chip, pulley and exhaust.

I doubt with all the engineering GM put into the sport compact racing scene in the summit sport compact series that some of that knowledge would not make it into the aftermarket for the Cobalt SS.

Remember that GM has been racing the cavalier with the Ecotec for a long time now.

Here is a link about the Ecotec in the GM FWD Drag Car.

"With the GM Ecotec global powerplant, we're making over 1,000 horsepower, and the majority of the engine components are production parts," said Josh Peterson, GM Racing Sport Compact program manager. "We're using a production block, production main bearing girdle, production cylinder heads, a production oiling system and a production drive chain. It's simply amazing what we can do with this basic engine package. We believe that we will ultimately reach more than 1,150 horsepower before we exceed the limits of the production parts."

"Many of the heavy-duty Ecotec components developed by GM Racing for the Sport Compact drag racing program are now available to enthusiasts through GM Performance Parts. These include complete race-prepared blocks, ported cylinder heads, steel billet crankshafts, connecting rods, pistons, copper head gaskets, aluminum intake manifolds, racing camshafts, neutral-balanced countershafts and intake and exhaust manifold flanges."
