Dynatek happy harley!
By Shane G. on Verified Purchaser
I had used one of these products before that is why I bought again. This 04 Super Glide had a glitch in the ignition with only 4000 miles on it. Replaced every component except for the module, did not fix the glitch. Installed the Dynatek module in about 10 minutes problem solved. The idle improved 100% and picked up noticeable top end performance too.
