I am running the 93 Octane tune on my 02 v6 mustang and i am getting bad gas mileage. Around 15ish. I have a bbk cai and a throttle body spacer. I checked both the WOT fuel menus and i am running on the lean side. any suggestions? thanks

ok. Im located in Upstate SC, would i need to go all the way to atlanta to get a tune? or is there somewhere near?

idk all i have on my car performance wise is a bbk cold air and a throttle body spacer (i know it is a waste). Could i just need a custom tune?

Ok so i was reading in a magazine that by doing a custon ethanol based tune with an 02 mach 1 the owner was able to get an additional 20 hp and 30 fpt and better gas mileage. It says that because of the up to 10% ethanol you have to run the car more rich. True? If so, are there any diablosport ...

ok thanks

02 ford mustang coupe. U7146 and idk about the revision. i havent upgraded it since i got it Dec 08

i was wondering how important upgrading my tuner and car would be and also what kinda of things would be changed?

ok thanks. i will look into.

Is it neccesary? How much would that cost?

i have a 2002 v6 mustang. I have installed a throttle body spacer, and bbk cold air intake, as well as the diablosport programmer. Is there any way i can request a custom tune so i can get the max power as well as GAS MILEAGE? Im getting about 20 mpg... not too great for a v6. Any suggestions? thanks

how do i access the short term fuel trims?

the only thing i have done is installed a high flow filter. Other than that no.

ok i fixed that im getting about 20 again stock. But still why when i install the 93 octane im still getting thirten?

I have a 2002 v6 mustang and after installing the 93 octane tune i began getting about 13 miles to the gallon. After figuring this out i immediately switched it back to the stock tune. Unfortunately, after doing this i am still getting only about 14 to 15 mpg. opossed to the 20 to 21 i had before ...

By fuel trims do you mean mpg (about 14) or do i need to find that information through my programmer? If so How?
