Sorry about all these Dyno/Tuning questions, but picking a tuner has proved to be harder than I thought.
Price ranges have run from $250-$525 with places I have contacted. I've been told "We can't work with SEPST, you have to switch to TTS", to "You have to expect some popping on decel"
The only mods to my bike are the Exhaust system and the S/E Air cleaner.
Would a dyno tune from an HD dealer be sufficient to make sure my AFR is correct to prevent running hot? I just want a smooth running bike with decent mileage.

 

Bikes with a stock ECM and no additional tuner only get limited downloads if i'm correct.
Aftermarket tuners have the capabilty of more adjustments with different maps or adjusted with the use of a dyno.
Some shops are limited as to which tuners they can tune.All depends on the persons knowledge of the device.

 

I went as cheap as I could go the first time. Save your money - Buy right the first time and get it dyno tuned.
No sense in spending money twice to get it right. Also with it dyno tuned you dont have to play with it all the time.

 

I already have the SEPST w canned map and plan on getting it dynoed. Just trying to decide if going for a 5+hrs $525 Indy tune is necessary with my limited mods, or will a 3-4hr $325 Dealer Tune be enough.

 

I had a SERT,A/C and SE slip ons installed on my old '06 Road Glide at 1K.The SERT only had a map download for the changes.The bike ran very good,averaging 42 MPG.
At the time I was quoted 4-5 hrs. from the dealer to do the dyno.I could not see spending that kind of money.
I finaly did do a dyno at 25000miles when I went to a 95".
A tuner with a good map or just a good download to the stock ECM should be fine with out having to pay for a dyno,unless it is not running well or poor fuel mileage,etc-.

 

Good tuners these days should have a computer full of maps...a great example is Jamie at FuelMoto. Do most people really need a 4-5 hour dyno tune for a stage I setup...no way! Even the HD stage II setup(95" or 103") with SE cams is so common, maps for those are readily available and may only need a few tweaks depending on the exhaust. Now when you start adding head work, radical cams, hi-comp pistons, turbos, blowers then more extensive tuning is definitely needed.

 

Thats what I was trying to say!

 

I would not take my bike to a dealer who says they cant tune with a sepst. This is a Harley part and after spending the money for it, they want to tell you to buy another one? Next dealer!. I have come to the conclusion that I am going to tune my bike myself since there are no tuners within 300 miles from me.

 

That's kind of what I was thinking. Down the road, if I add cams and head work, then I'll go for the big $$$.

 

I went with the HD Stage II 103" upgrade and all they did was flash the ECM. All this Dyno Tune stuff is rubbish. There's no need to spend all that money. My bike runs very strong and doesn't overheat. I'm as happy as can be with it.
