I wouldnt run it. Im not a fan of "chips" they are just computer foolers that make it think its seeing something different and make mor epower. I'd rather get efi live from Fleece performance and have them tune the car.
Chip Express Tune 200 horsepower 348 ft-lbs of torque
I was wondering if anyone had used this chip. I'd probably wait until the car was well broken in (like 10,000 kms) before getting one, but I wanted to know if anyone out there had any experience with it? It looks decent and appears that you can set it differently so that you can have more of a conservative tune or run it all the way up to 200 horsepower and 348 ft-lbs of torque. It's expensive, but for 50 horsepower and like 80 ft-lbs of torque, if it didn't cause the car to blow up, it could be worth while. Here is the link to the website.
Diesel Tuning Chip for Chevrolet Cruze 2.0 VCDI 150PS / 110kW / 148bhp
Edit: Also found this chip tune website. Anyone know anything about it? I have looked through the forum but can't seem to find a whole lot of info on tunes for the Cruze diesel.

It appears that this is something similar to a bully dog tuner, which works well in Dodge vehicles. CHIP is the name of the company in this case, not the tuning method.
That said, the website appears to be based in the UK, and out vehicles are a bit different than those. I wouldn't buy one unless it was demonstrated that it was both safe and effective on the US Cruze.

Given this is sold in the UK, it is likely meant for the European spec 2.0L diesel Cruze, which is an entirely different 2.0L engine than the U.S. spec diesel Cruze.

Only tuning I would buy would be EFI Live. Period.

It has an option so you can select the European spec Cruze or the UK Cruze. I think I'll just drive the Cruze stock for a while and give it some time and see if anyone in the US starts by this tune.

I was wondering when someone, or many, would come up with a tune for the CTD. I would imagine there's a ton of HP left in these engines and a tune would certainly bring it out. I read a little about the EFI tune and it seems it makes a lot more HP, at least on the dyno. I would be afraid that transmission, differential and other components might not be built tough enough for that much HP. Without limited slip, I'm not sure you could put the power to the ground. I'd sure like to see what the "tune" does for acceleration times. I wonder about the Aisin transmission and how tough it is???
I added several thousand dollars worth of bolt ons on my Corvette and had it tuned afterward. The tune seemed to pull everything together and added another 19 HP on top of the other stuff. In the end, I was up about 60hp over bone stock and dropped more than a second off of my ETs at the drag strip.

Bully dog tuners are not "good tuners" I have taken efi live training classes and the tunes that they use in a nut shell result in add more fuel, bump timing way up and it will create more power. but its not good power. Its someky, the engine doesnt run as smooth and the longevity is affected. CHIPS in general which is what that is and the name of the fools what the computer says. it takes certain values and lowers or raise them to make the computer supply more fuel or raise timing for example. Efi live tunes you can smooth out the fuel maps and make them run way smoother and get rid of ridges in the tunes so the power doesnt plateau or drop off. Efi live cannot be beat in tuning. Also tunes can be customized for each individual vehicle and youre driving habits. bully dog or other tuners whuich just plug in are a mass produced product that works for everyone so they cant accomodate a different trubo or air intake or injectors.
To the OP I would invest in EFI live if youre serious about getting youre diesel tuned up.

Both my former TDI's were chipped, and it's a world of difference. It was astonishing how much better they were, and if you can keep your foot off the fun pedal, the economy's about the same.

Definitely can't say whether this is true or not because it is on wikipedia I found this information, but apparently the stock transmission in the Cruze is rated for 325 ft-lbs of torque. As I said before, I'd want probably 10,000 km's or more on the car before I started playing around with it. This car is by far the most expensive thing I have ever purchased, so I don't want to screw anything up. I'm sure in a year or two, the aftermarket will have grown a bit and there will be a better idea as to what some good products are and what some not so good products are. Until then, 151 horsepower and 280 ft-lbs of torque when in overboost is more than enough 
....I was just curious as to whether or not anyone else had tried one of the canned tunes.

Anything that comes from GM and has a diesel, EFI is the best route. Anybody who i familiar with Duramax trucks with know this to be a fact. The two company's who have tuning out now or who are in the process (Fleece, DuramaxTuner) are two of the best tuners for the Duramax. You could not pay me to buy anything else for a GM diesel car then what these reputable tuners will/have came out with.

I can't wait, I bought mine just for commuting but would love some more grunt when I get on it.
I am fine waiting until a tested and true tune is available.

If you're not using the factory over-boost frequently, then there is no point in power tuning - you're not even using what you got now.
Here's the transmission specs from the GM Powertrain web site:

AWTF-80 SC - Wikipedia, the free encyclopedia
Once again, just a wikipedia fact, so it can't be for sure credited, but it says that the transmission is designed to handle a maximum of 440nm of torque, and its max shift speed is 7000 rpm with 350nm or less and 6500 rpm with 350nm-400nm. So if wikipedia is right, with the Cruze only shifting at 4500 rpm, I could see the transmission easily holding up to 440nm of torque, which is about 325ft/lbs. Maybe a bit more. Before I get flamed for saying that though, I'd like to clarify, I am just going off what Wikipedia said. The GM Powertrain Website is a much more credible source than Wikipedia.
my feelings as well !!
Aisans own site lists 325ft/lbs of torque as the max rating for the tranny. As I believe it was 70Acc...something pointed out awhile ago in another thread GM is notorious for rating a transmissions max specs right above the output of whatever engine it's paired with in their own documentation and that seems to be the case here as well.
Did anyone else notice Fleece has oversized injectors available for the cruze on their site right now....
