There's not much consolidation of information between this and the Sol side so I figured I would try and type out everything that is a known FACT about the GM Stage 2 at this point. I'm running on little sleep so if I miss something let me know :lol:

Availability:
It is current available through Crate Engine Depot, GM Parts Direct, and your dealership. Prices are a little crazy since we have been told GM bumped the price, GM Parts Direct has S&H charges that put it at about the same price as crate engine depot. Price as of 12/17/08 is listed as $550 at crate engine depot. Dealerships do not have it in their part database yet, but they can order it. The systems are updated at specific intervals throughout the year and have not been updated since the parts release. It is part #19212670

A dealership has to install this part due to the necessity of a tech 2 programmer to flash the vehicle's ECU. They will probably charge 1 hours labor to flash te ECU, which it should only take 1 hour to install the whole kit, so why do it yourself?

Currently only available for 07 and 08, 09's are awaiting CARB certification and should be available spring.

Performance:
290hp/340lb.ft for the manual transmissions
290hp/325lb.ft for the automatic's

The one person who has it installed that we know of, a GM Engineer, has reported an overall increase in gas mileage. Manual transmissions get the no-lift shift feature (during heavy acceleration you can push down the clutch without taking your foot off the gas to shift) that helps maintain boost during hard shifting.

The new ECU programming no longer learns down aftermarket parts. For example, the installation of an exhaust on a redline previously gained around 15 horsepower upon installation but after a few times driving the car has reset itself back into the factory power numbers. This no longer occurs.

Those numbers are at the flywheel, NOT wheel numbers like the other tunes, this means that other tunes are putting out more power based on the official numbers. We do not know if the aftermarket tunes are overrated, and there is the possibility the new GM tune is under rated. The GM tune has the potential to be much more in time since the new sensors are good for 300kpa which is 28.5-29lbs of boost. The stock turbo is not capable of putting up those kinds of numbers, this tune will be especially relevant for those with turbo or wheel swaps.

Rev limit is pushed up 250rpm, should allow for 0-60 in a single shift (second gear).

Claimed performance increase:
Production Solstice GXP Manual Trans (near standard ambient conditions)
0-60 5.4 seconds
1/4 mile 13.95 seconds @ 99.5 MPH

Solstice GXP Manual Trans with Performance Upgrade Kit (no other upgrades, near standard ambient conditions)
0-60 4.95 seconds
1/4 mile 13.65 seconds @ 104 MPH
Should have actual dyno results this week (12/17/08) from a customer taking his car to performance autowerks.

Warranty:
Your Sky's warranty is kept intact by this tune. The parts themselves are warrantied for as long as is remaining on your drivetrain warranty or 12,000 miles, whichever is LONGER.

Installation
There is currently many reports of dealerships not knowing how to do the flash without calling in, as well as dealerships charging for 4+ hours labor. GM expected install time is <1 hour. A customer has self-installed the sensors with the factory tune and it works for simply driving from point to point, but has not been tested under boost.

Misc:
Tuners are able to work within this new tune through existing software! Tested on an HHR.

Guranteed 50 state emissions legal, and has passed CARB certification.

NEW INFORMATION WILL BE ADDED TO THIS POST

Good idea to get a cleaned up central place for the Stage 2 details. Sure, I'll sticky it. We may want to continue to quote in some of the key posts about it. Folks should weigh in on whether as a community you want us to filter out feedback to keep the thread as a dense FAQ style thread or just let it run as it will as a general discussion.

The original poster should edit the first post with the facts as necessary. That way, all you do is read the first post for the facts. Any other posts should be for like something to add or something but there should be no "update" in later posts. When that happens, things get hard to find.

I'll keep it going with new updates.

Question -- can you clarify this?

Despite no lift shift, this tune is most likely going to be slower than a previously flashed car.

Are you saying that the GM tune will be SLOWER than a stock car that has someone ELSE'S tune installed, or slower than stock?

I vote that we keep conjecture and banter out of this thread- there is plenty of that in the other (very long) thread.

Rewritten so as to continue to be a fact based thread. I apoligize for the conjecture in the OP.

Reread that section, it makes more sense now. The advertised HP numbers are lower than those advertised by aftermarket tuners. Until two tunes are on the same car on the same dyno in the same conditions we won't have a 100% accurate comparison number.

As long as whats current and concise is at the top in the first post, there's no need to read the other posts.

Until someone else has their hands on this tune and checks it out I would venture to say that this tune is also conjecture. :eek:

Crate Engine Warehouse has already shown pictures of the packages he got in (and sold) as well as Flash's Owner having the true first production install

But I get your point :lol:
