hey, i'm just as poor as the next poor college student, but hey what's an extra 15-20 cents a gallon for premium. i mean @ 21 gallons for my explorer its like 4 dollars max every 2 weeks, for the extra power, i absolutely love it, i step on it, and boom, instant downshift, instant power, plus it removed the programed speed limiter, haha, no more cutting out at 108 mph!!!
