With DJ's Economy tune...I can still smoke most things...you just have to floor it to get any power.
I have seen 2.5-3 MPG improvement with DJ's Economy tune. I have seen 1.5-2 MPG increase with DJ's street tune. I am seeing 2.5-3 MPG increase with the Looney tune. All of those numbers are while being very light on the throttle.
i havent ever really ran economy tunes...i guess custom ones are better. but i have always gotten better mpg on higher powered tunes. i wouldnt think the race, but street yes. more power=less throttle to acheive the same speed. so if you drive it right, the higher powered files should give more mpg. i used to have a banks six gun and i would always get better mpg on the highway in level 6 than i did in level 3-4!
