really bad mpg

I dont know what it is but ever since i straight piped it i have all the sudden been getting horrible mpg. Tried 2 different tunes and nothing changed. Last time i got bad mileage it was because my turbo went out but i dont think thats the case this time. Any suggestions?

well i know the computer is off a little bit but it shouldnt be as bad as it is. right now the computer is saying im getting around 8mpg so i would say im really around 10 give or take. But it is a significant difference after i straight piped it. That wouldnt make any sense that just cutting the muffler would do that so i dont know. I use the tunes from innovative and switched from xtreme race to street and adjusted some of the options so im thinking that could be a possibility too. Im in Tuscaloosa right now but im from Dallas.

It has nothing to do with strait piping. Maybe you love the extra power and noise and you have a heavier foot now??????

No there is really no difference in power its just louder but i haven't really let that factor into the way i drive it. I have also noticed that sometimes the engine makes a whining noise in the 1500-2000 rpm range

I ment power from the sct! What kind of whining noise? If the fuel mileage dropped with the new tune i would switch back to the old tune and if mileage is back to normal i would call up innovative!
