SEPST can be completely tuned on a dyno very similarly to a SERT. Both of them also have the capability of data recording, providing the user with data for street tuning. Some dyno operators are more comfortable with one, some are more comfortable with the other, and some are more comfortable with Power Commander products like the PCV or PowerVision.

The SEPST is the replacement for the SERT...it is intended to do what a SERT did. "SERT" is no longer available. It is now TTS. "SERT" stood for "Screamin' Eagle Race Tuner." Since Harley went with another company to write the tuning software (SEPST) the SERT could no longer go by that name because Harley owns the rights to the name "Screamin' Eagle." So the company who writes the "SERT" Harley tuner changed the name to TTS.

Again, the capabilities of both products are similar and they are in direct competition with each other...hense the Harley dealer saying he'll honor your warranty if you purchase the SEPST but not if you purchase the TTS.

Ask your dyno operator which tuner he is comfortable tuning with. He may be comfortable with both but might have a preference or he might only be comfortable with just one of the tuners. Either way, you'll need to make your decision after gathering that info. If he will only use the TTS, then you have to choose between your dyno operator with TTS or your warranty with SEPST.
