    NIGHT AND DAY DIFFERENCE! I had an ebay tune in my M50 with minor mods (intake header exhaust) and it was okay but it really only felt slightly different at wide-open-throttle. Finally decided to go with a real tuner and WOW. MPG went from 25 average to 30. Power is incredible everywhere on the throttle, not just wide-open-throttle. And it pulls so much better than before. There’s seriously no comparison. Incredible. Such a big difference I bought ANOTHER tune for my S50B30US (which is also amazing and blows the previous RK tune out of the water!)
