Several years ago I bought a power commander V tuner and highflow air cleaner from Fuel Moto. They sent it pre-mapped for my setup, which included the above and V&H Monster Oval slip-ons. Otherwise the engine is stock. When I first got it, I thought it ran great. Lately, though, it seems to really lug at low speeds and I'm wondering if somehow the tuner has been reset or lost the mapping or something. Is that possible?

If so, can you guys point me to some very basic instructions as to how to get it running right again? I'm confident the guys at FM will re-send me the map but I'm doubtful I can even find the disc. Can I download the program someplace?

Any other suggestions?

Thanks!
