I object to this. I ordered a custom 87 performance tune and my mileage decreased by 3-4 mpg. That is 75 to 100 miles per tank. For me that is 3-4 round trip days to work. My driving habits did not change at all. Needless to say I have been running on the canned 87 tow tune. I was going to ask this in a new thread until I found this one: Is it possible to run the canned 93 performance tune with 87 octane and lowering the timing by 3.00 without causing any damage or having any trouble?
