Well i have the program all hooked up and def can tell the power change! Getting lot better gas mileage to. I been running in level 2 which is tow on edge. Has a total of 4. I do have a question though. I can put it on level 3 and pin it and it will go through all gears no problem, shifts a tad hard. Level 4 though will do the exact same as 3 and haul ass. but soon as it shifts to over drive. it will kick it out of overdrive and then engine light will come on. Just curious whats going on, is the tranny noticing to much power so it kicks it out or something? Oh and i can drive in level 3 easy and shifts perfectly fine. Thanks Joey!
