The new HD tuner will be available at the end of the month and I was wondering if anyone new much about the SEST. Of course I asked the men behind the parts dept desk twice (two different guys, on different days) and got two different answers. One said wait for the new, and the other said get the old SERT. Anything?

 

I have been wondering the same thing recently. The best I can tell by reading the Screaming Eagle catalog information... the sest is geared more toward being compatible with EPA compliant configurations and the sert is more compatible with performance machines. I have a friend that really likes his sert.

 

thats what i understand but also the sert is for off road use. just like my exhaust. they made it to cover them selves with the epa, same as TM 50 state

 

What is the new tuner?

I have the STSE PRO, the orange box that replaced the older black one. Part number 32109-08B

 

Screamin eagle race tuner--the old; Screamin eagle street tuner; the new.
