[QUOTE="myzen, post: 533479, member: 15246"] You can get the Thundermax for about $650. The biggest difference is the TMAX completely replaces the ECM in the Harley. I ran one for almost a year. The biggest problem with it is it doesn't retard the ignition so pre-ignition (pinging) occurs. I ended up going back to the stock ECM and a Screaming Eagle RAce Tuner (SERT) and found the performance to be comparable, plus the peace of mind of no pinging. The Motty is cool because it is a piggy back design and does not eliminate the stock ECM. I like it and will be watching this thread. [/QUOTE]
