I recently did some exhaust mods to my Roadmaster and decided to purchase a DynoJet PV3 to get the right tune. Craig from Fuel Moto sent me 2 tunes. I tried both and they inhibited my idle and the bike would die at full stops intermittently after warm up. When I let him know of my issues, he sent me 2 additional High Performance (HP) tunes. Both greatly improved my bike performance, but still had the idle issues. He then suggested that I revert back to the original stock tune; which I did. It ran and idled fine and had no issues. He then mentioned that he needed to provide me with tunes that would improve my performance and correct the idle issues or in his words "I had just paid $399 for a door stop". He then sent me two more HP tunes that had the stock settings for idle. They both work GREAT! The performance increase is fantastic and the idle problem is corrected. This all took place in one day. Craig stayed with it and wouldn't give up until the customer (me) was satisfied with the PV3 I'd purchased. Cudos to Craig and Fuel Moto!!!
