i got mine installed @ 2011 sturgis trip thanks guys (installed on a 2010 dyna street bob)

Adding a Thundermax to my 2009 Fatboy next week. Sick of the back throttle popping, and sluggish acceleration. I have spent hours viewing the website and link. I am now convinced Thundermax compared to SE is the better option - Thanks for the recommendation Shane @t Heavy Duty Motorcycle, Brisbane, Australia .

An air cooled engine can greatly benefit from a lower idle speed. The engine will make less heat at a slower speed but there are several factors to concider. Anyone attempting to lower their idle needs to consider stability in: Oil Pressure, Charging voltage and Idle smoothness

You will find hundreds of You Tube videos from around the world highlighting slow idle in speeds of 550-650 rpm. Our approach would be more conservative, with speeds in the 700-800 rpm, to provide a good balance of all above-listed concerns. In most cases lower idle speed using a ThunderMax system will yield the smoothest idle, which your engine will love.

Ive had a custom map installed by a dynotuner through a CERT , i think the idle is slighly fast for my liking. Can i install a thundermax and will it fix the idle (among the other obvious advantages)?

I have seen many Thundermax users drop their rpm to below 600 rpm (560+) on Youtube. Is this advisable or would you recommend 1000+ rpm?
