Ok, those of you with the superchips programmer and the 4.7 I got a question, how much of a benefit do you see with just the 87 octane program? I know it is no where near the benefit of the 91 octane program, but is it fairly noticeable, do you still get the full torque management reduction? Do you get better mileage then when not using the programmer? I really want a programmer but would likely not be able to fill up with 91 all the time and just wondering if it is worth it if i will be running the 87 program a lot. Thanks
