Thx what I needed to know. I really don't try to compare. Just makes me wonder at times what is he doing different. I found my car seems to run better completely stock also and even though something makes me not want to admit it(Already bought the "snake oil". I still try things like the K&N and plug gap changing in hope for some miracle "drug". I even bought that group buy tune and I am not using it(not sure why I bought it) peer pressure? Right now I have the K&N in my car and .035 gap and I have @ 100 miles on this tank and I am looking at 40+ on the DIC all highway, so I know it is where I drive. All the cars I have owned(10 new ones), I have never modded them and just drove them till I got bored and bought a different car. I am thinking of calling my dealer to get another stock air filter and going back to the basics I am not a road racer!The cruze I drive is completely stock. However I am interested in experimenting with a less restrictive air intake as well a straight cat back exhaust. Im curious if I would be able to slightly increase my mpg, at 50mpg even 1 more mpg would be a success. Im not interested in horsepower or noise. Speaking of noise even after 145k miles the interrior still hasnt developed a single rattle, vibration or irritating sound.
I doubt your car has any issues I just drive under ideal conditions at 50mph with very few stops. So you shouldn't really compare your mpg with mine. In a major city and long distance driving on the east coast 44.6 mpg is a win.
I'm glad you see the truth, if there was any MPG mod or tune that could be done for so cheap GM would have already done it to the car from the factory. There are so many variables when it comes to MPG it would be hard to prove or disprove any small changes people see. Honestly the biggest thing is the route and driving style over everything else.I found my car seems to run better completely stock also and even though something makes me not want to admit it(Already bought the "snake oil".
