Perhaps it was a loose chain that was making me feel a slight hesitation and then a gripping when in first gear. I'll still go for a tuner and dyno tune eventually, but at least I can now wait until I'm flush and enjoy my ride once again in the meantime..

PCV with auto tune will tune itself.

TTS mastertune

YOu need to find somebody that knows the unit and knows how to tune with it.
And everychange you make to yer motorcycle, you need to go have it redynoed again.

The Thundermax with Auto tune, You replace yer stock HD ecm and use the Thundermax ECM and wide band oxygen sensors.

I'm not clear on something. The PC V auto tunes. Is that a fine tuning after a dyno, or does that mean you skip the dyno tune?

The map you git with the PC is a close map, you don't have to tune.
But I like to make sure the timing and everything is closer and let it tune from there.
I rode for many months without tuning the PCV.

The Thundermax unit I like much better cause its not a piggy back unit.

i would contact the mfg. get the straight scoop.....you will ge many different answers. ask the same question to the mfg. an autotune of any brand should not need a dyno....jmo. i am not fluent in efi so this is just speculation. the word auto tune suggests to me that a dyno should not be needed.....let us/me know what they say..........

One of the most important thing in a Map is the cam.

If the right cam is not chosen in the map the timin might be off. This is a big factor.

So when you take a bike with Auto Tune to a dyno person, you need to tell them which cam you have and the mods.

If you have the cam specs that will even be a Plus.

Then the auto tune can better do what its suppose to do.
What auto tune can't do is change timing , it changes Afr's by reading the o2 sensors
