how good is the mileage with the mail order tuned out of the box.. i will be doing some dyno pulls

 

^Bump, I'm interested to know this too.

 

I get 35+ on the highway

I get 25ish City...

round abouts I get about 24-26 mpg average

 

Is this with a SC or TC. I have been reading that the SC tends to get better MPG. I would also be curious if the MPGs changed with various tunes like HPTuner, Trifecta, Superchips, etc. Since I drive 53 miles to work each way, I am hoping that my 28mpg average (75% highway) won't drop if I am taking it easy on my 2009 SS/TC. The reasons I got the cobalt ss was for the power and the gas mileage.

Thanks,

Rich

 

I've been averaging 26.7mpg mixed driving...With a lot of spirited (yet controlled) runs here and there. I've logged my fuel economy since tuning and have thus far averaged about 3-4mpg more since.

 

u mail tuned tofu??? k i cant wait to get tuned with my intake/exhaust

 

Negative sir, just have been tuning via HPT.

 

I have a street tune done on mine and gained about 3 miles city and a whole lot more highway. I'm around 22 city and 37 highway

 

I have a TC now... my SC did get much better gas milage... but due to the D/I good gas milage isn't really going to happen!
