True, percentage-wise they're actually better. My HHR SS gained about 25% horsepower and similar torque, the Cruze was 31% HP and 38% TQ.

Aw, c'mon. Everyone loves a dirty girl... well, mostly everyone

Nice results. And did I read that correctly? LSD standard? And why wasn't this a STANDARD on the Cobalt SS????

I think it has LSD - seems like GM is putting that in everything now. My 2010 Buick LaCrosse had it, also.

Let me put it this way - when i floor it, both tires spin. I'm assuming that means it has LSD. Haha

Not necessarily. This car doesn't have an LSD-

Update: I received a phone call from someone today who wanted to know what kind of 0-60 gains we achieved with the tune. I told him that it was a good question and immediately headed out to the car with my laptop.

I use Palmer Performance's ScanXL for logging, and it has a virtual dyno and virtual drag strip feature (both work really well). The virtual drag strip also gives you 0-60.

I only did two tests - once with the stock tune and once with our custom tune. On the stock tune it told me I had an 8.6 second 0-60. On the custom tune it said it was 7.2 seconds. After doing some searches on the internet, one website claimed they got 9.6 seconds 0-60 on the LTZ model. GM's press releases said "around 9 seconds" with the automatic transmission, so 8.6 seconds is probably close to accurate.

So, I'd say the relative gain was 1.5 seconds 0 to 60, give or take

Not bad... But I wouldn't trade my car in for these. No power... I understand what they were aiming at, but a 4-cylinder turbocharged engine that's GREAT on gas & still can roast the tires in 2nd gear is an amazing feat! I LOVE my SS/TC.

Man this is all such good news.

If i had to get a family car the Cruze would be up there.

Looks like the 0-60 is on par with a 2.2 cobalt.

Do we know how much boost the tune is pushing? Also do we know how this effected fuel economy?

7.2 seconds from 0-60 with the tune that's really close to what the SS/NA with an automatic trans does stock. The Cruze weights a lot more than the Cobalt does so you could defiantly improve the time by shedding some of the weight.

Around 22psi of boost peak. Initial economy tests show no effect on economy during typical cruise, but obviously it will use more fuel at WOT.

We did some transmission tweaks that should improve economy as well.

I actually shortened the shifts to around 5900 RPM (instead of 6100 RPM), did a new 0-60 test and got a 6.8 second. I'd like to test under more controlled environment, though. Maybe next time I'm at the dyno

So I FINALLY washed the car over the weekend, and took a picture of it. It's not a great quality picture but it's a good place to start I guess.
