For SoCal,
I have had my bike tuned by three shops. It's an M&M '01 Ultra with 95", .203 cams, SE intake, true duals, and free flowing mufflers. It has always been a bitch to tune, and never ran right. It pinged like a can of bolts. I've been through two TFIs, a PCII, a PCIIIr and finally an SERT.
Gary Bethurem at World Thunder Empire
http://www.worldthunderempire.com/worldthunder.html, did the SERT dyno tune with it. The bike runs better than it ever has. Every other place needed the bike for a whole day. Gary did the MAP while I waited and had it done in about three hours. I'd go to him again.
Danny at Glendale HD is pretty good too. He came very close when he tuned the PCIIIr, but my mpgs were poor. He was my first choice to tune the SERT, but he was all booked up. So I went with Gary instead. I'm glad I did, I am very pleased with the way it turned out.
Cullen at Bartels HD did an okay job with the PCIIIr. He's a nice guy and all, but I don't think he comes close to Gary and Danny. His tune was so rich my mpgs were horrible.
