His name is also Jay. He is a great guy to deal with. You need to send him your can as the torlerances are slightly different from one can to the next. It took about a week or so to get it back. The sound is great. A bit quieter than the with the stock Termi DB killer but definitely louder than the stock dual pipe system. And the best part was not more whistling. His email address is email@example.com. And yes, I am still having some issues with low rpm fueling after the reflash as well. Im thinking about putting my fat ducs back on which i removed before the reflash.
