Best investment ever for my bike!!! A 99 Road King with old MM EFI. A few years ago purchased their original open loop system with Zippers 50mm throttle body. Ran perfectly from day one.
A few months ago changed over to the latest closed loop system w O2 sensors. Again, absolutely flawless performance.
Will be a Daytona for bike week if anyone wants to check it out.
Thundermax with A/T is a true tuner. It is the 1st thing I would do to any bike. I ran one for a year with no problems. Have the one I took off my 07. Gonna git one for my 08touring as soon as they are released.
I've got one, but it's not installed yet. Hope to get to that this weekend. Along with a Fatcat, IDS, shifter linkage, K&N air filter and Kuryakyn grips. I wasn't that attached to my wife anyhow.
