Glad I am not the only one confused...

The full version of the SE catalog has good explainations.

The Pro Super Tuner is an updated version of the SERT. My wife's 08 has a SERT and my 11 has a SEPST. The SERT/SEPST allows you to tune to your specifications.

The Street Performance Tuner basically lets the dealer download Stage 1 type EPA compliant ECM calibrations.

 

the sepst i have on my 08 streetglide works great. i haven't had any experience with the sert, but the sepst is supposed to be the latest version of harleys tuners. mine has the little box that can record an amount of time to show you how it's running, via downloading it into the computer, and then it allows you to tweak the tune if desired, as far as i can tell anyway. i know that the power commander V, after two wrong maps, i sold it and went with the harley tuning device instead, dyno tuned it, and i'm very happy with it.

 

When I had my SERT equiped bike Dyno'd in late 2009, the Dyno Tuner offered to sell me SERPT. Said SERPT was more versatile and would give me quicker response on the throttle? Wasn't in the mood to drop an extra $400 for faster throttle response. SERT serves me well.

 

sooooo.......a tuner who is proficient in TTS Mastertune is likely equally good using a SEPST? (Screamin Eagle Pro Super Tuner)

 

You can buy the software, cables, and training CD for under a $100.00.

 

It is my ability to comprehend and utilize the cables and training software that concerns me.
