So we all hear it if something improves performance it decrease MPG right? Yes and No.
Now i drive 2010 cobalt XFE 5 speed said to get 25 city and 37 highway. I also drive 75 miles a day so i am feeling my wallet getting smaller when ever i fill up. so i decide to do some test and find out if i could get some more MPG.
i started of seeing what i can get driving like a grandma i got around 37.5-38avg MPG witch i thought was pretty good. then I lowered my car and ordered an underdrive pulley with driving habbets unchanged. Now im getting 40.8-41.3 Avg MPG witch is even butter however its a lot harder to drive like a grandam now that my car is faster and handles a lot better XD
