se tuners
IOW, don't waste your $ on the Street tuner...
If you're interested in DYI, you might want to look at another option like FuelMoto's PowerVision as the SEPST isn't very user friendly.

So I went with the SERT and stg 1 at the 1K. with a dyno tune. I love it. I don't have to mess with it and it was perfect for 15k when then I added the cams . Got a winter cam job that included a FREE dyno tune after the install.
Now with almost 46 K and 7 yrs old our SERT tuned bike has been totally trouble FREE. I haven't had to touch the tuning other than those two dyno's.
Son has had 3 new bikes since 07, all three with stg1 and cams. The 07 had the SERT and his 09 and 10 had the SEpST and he's had narry a prob with any of them..
He's sold on the tuner as I am. If,,,, I ever get another new bike, I will for sure tune it with the SEpST.

But I'm not 100% sold on the dyno yet, although I'm beginning to move in that direction...
I have the SEPST (including cables and software) and the SmartTune feature is basically useless for the end-user, unless you have access to Daytona or Talladega.
After I had the Stage 1 done, the bike ran better but hotter than hell - MPG fell off too, and on top of that the decel popping was worse than ever. ViED's corrected ALL of that but they're more of a "quick-fix" instead of a long-term solution.
There's just so many variables here that how can I know if the guy doing the tune and I are on the same page?
I get the feeling from talking to the service guy here, that if dyno'd they'd still be obliged to maintain EPA standards, meaning still way to lean...

There's another good sticky thread there that lists questions to ask your tuner. Basically you want to ensure that they are going to set up your VE numbers correctly before moving on to the AFR and timing tables. Too many of them just take the system out of closed loop and adjust the AFR to maximise full-throttle performance curves, leaving your bike running shitty for 95% of the time.
Your HD dealer is not a tuner. They will most likely stick a stock tune on and call it done.
