Anyone with experience with one of these units lets hear it. Reads real well for adjustability and cooler running.

 

I have one on my 08 ultra. it did cool down the exhaust, I installed it on my stock bike just to cool that beast down. since I have installed pipes and a air cleaner...just started from the setting recommended on the instructions and the bike runs fine. did lose some fuel economy but thats to be expected with a richer mix..

 

I considered one for my '08 UC. As this unit (and others like Dobeck) only adds fuel, I wanted/needed a lot more control. Yes, you can dump in enough fuel to help cool but that is only part of the issue.

I passed on the Cobra and went with the TTS.
