Bike starts and idles. try to ride it and runs like shit. Guys at Thundermax were not willing to talk to me last fall. Thunder Heart didn't return my call. Anybody try this.

I THOUGHT THEY MADE STUFF ONLY OR MAINLY FOR HARLEYS. I HAVE THE THUNDERMAX AUTO TUNE ON MY 08 STREETGLIDE AND IT RUNS GREAT. DID YOU RELOAD THE BASE MAP?
