Following this thread : http://www.cruzetalk.com/forum/201-...cussion/196210-small-changes-reduce-heat.html

And after chatting with Corbin Murphy @ Fleece, i wanted to know how much power my car was making and if the 50hp tune was indeed stronger then the Race tune. (The tune you get when you delete)

So Corbin made a Tune that "should be the 50hp tune scripted over what you had." (The 50hp tune is one of the 3 tunes you get when you just tune a stock Diesel)

So here are the results : Land vehicle Vehicle Car Chevrolet cruze Motor vehicle

1st of all, if you look in the picture where you see my car, on the blue shield its writen Mustang Dyno, so these are good numbers. The guy there never did a Cruze, didnt know Diesel existed and was quite impressed.

I was right! The 50hp tune is indeed more powerfull then the Race tune, but the amount of BLACK SMOKE you get is ridiculus, lol. The guys at Fleece did an incredible job on the Race tune to make it this powerfull with almost no smoke. On the Graph you can see the difference between the two tunes.

181hp and 296lbs of torque at the wheels for the 50hp dirty tune. The torque punch earlier too, its quite violent and funny when you drive.

173hp and 286lbs of torque at the wheels for the Race tune. Smoother driveability and no smoke.

Conclusion : I will use the 50hp tune only when i go Drag racing or to do stupid things. Its not worth it on the street for the difference with the Race tune.

I just got my Trifecta tune today, initial notice of driving was positive. Definitely smoothed out the stock lag, and some nice mid range torque added.

Any issues with the ez flash connectivity?

Nope, loaded in 5-6 minutes
Likewise when I did mine in December. Quick, like my Cobalt, though the trans tune uploaded way quicker.

Still turbo laggy off the line, but the pull mid range if phenomenal. Cruzed at 60MPH this morning into work and was averaging just under 60MPG... so that's good (y). Now I need to change transmission fluid to smooth that out.....

That's what I noticed with ours.

We had a 52 MPG tank at the end of February (30% city), which is far better than anything we've ever gotten on the same trip in February. It wasn't brutally cold or anything, but it still was like 35-40 degrees.
