The ECO model also has a special manual transmission, although the 6sp auto is an option for it.

According to my brochure (unless I read it wrong), the manual transmission is only available on the 1.8L non turbo version, and the ECO version.
I would personally prefer to have a manual transmission but I need at least one 6sp auto in the family to tinker with

That's a good question. Tuning is likely part of it, but there are some mechanical differences, also. The ECO uses low rolling resistance tires, different aerodynamic body panels, and a shutter system in front of the intercooler to reduce drag under certain conditions.

Update:
I was at the dyno again on Friday, but I didn't get a chance to put the car on the dyno due to needing to sort out some torque management issues. Those issues have been sorted out, the car is running nicely at 15psi (about 3psi over stock). I hit 18psi when I was still working on the torque management issues and popped a boost sensor out of range code, so I'll be looking at the diagnostics for the boost sensor next.
These new ECMs have a very accurate torque calculation system in them. According to it, the torque has increased about 15 lb-ft by nudging the boost up. It's a start!

It's a 2.76bar sensor like the LNF, and interestingly enough the MAP is the 3bar sensor used from the GMS1/LNF kit, but they never expected the absolute pressure levels to exceed 210kPa or so, so it's tripping the diagnostic and limping out. Haha

The stock OS may not have the maps scaled to run 3 bar pressure even if the sensors are the 3 bar bosch sensors. Might need to adjust the map scaling so you can run above 210 kPa

Yeah, I am pretty sure once we fix this issue, we'll run into something else. In software engineering, this is called "peeling the onion". Haha.

MAP voltage output vs absolute pressure probably needs to be rescaled, or even better the operating range needs to be extended if 210 kPa is not a hardcoded ECM limit.

What happened to getting those pictures?
I hate the Cruz with an undying passion. Makes me feel like GM is just shitting on the people who bought Cobalts(LS and LT). They come out with a much improved car for the same price. Means they raped us on ours. They will KILL the resale value of base Cobalts. The only ones worth anything now will be the SS's. I'm sure I'll get F-ed when I trade in for something else.

It's just a trade-off. Even if the Cruze is better in many ways, the Cobalt easily out-performs it dollar for dollar. SS/Ts give you a turbo, direct injection, variable valve timing, and great handling all in a car that can be found new for under $20k. I would hardly consider that getting raped.
On a personal level I really like the car, and I like it tons more than the 2010 Buick LaCrosse I had for business use before the Cruze, but for performance, it's not even close to what the LNF can do. And to be fair it wasn't designed to.
However, the LaCrosse, Cruze and the Regal are ushering in a new era of ECUs for GM vehicles which we are interested in. That, and the rumor is that the upcoming (if it goes to production) Aveo RS is going to use this 1.4L turbo engine.

Totally agreed.

What's the story with the Buick Verano? Is it going to use the same drivetrain as the Cruze?

All of the new vehicles are using a new set of "turbo aware" controllers from Delphi (the E69 is finished, other than use in the 3.6L LLT engine in the new Camaro, Buick LaCrosse and a few others). The Regal is getting the E39 which is SIDI capable, and the Cruze gets the E78 which is designed for non SIDI applications.
We're ready to go on both of these, and everything we learn about tuning the Cruze will apply to tuning the Regal as well.
Not sure on the Verano. Wiki says it will use the Delta II chassis but doesnt give any more information about the powertrain.
