I would go fuel moto, I didn't realize the perks when I bought mine and I think i went through amazon or another vendor. I saved a little bit of money but have to use power vision maps. I even emailed fuel moto and asked if i could purchase a map from them but they weren't willing to sell me one since I didn't purchase through them. And to be 100% honest, I can't tell/feel any difference from stock tune to power vision tune. I run it anyways because I'm hoping the tune is helping the motor run better and provide the fueling it needs. It seems to run well but feels the same as when I had no tune. Not sure if I wasted my money getting a tune period or if I should have went through fuel moto and got a good tune.

 

Thundermax auto tune...Money well spent..Install it with a base map and your done .The t-max will then tune your bike for ya..
I've had t-max on 4 touring harleys and they all ran perfect..
My opinion,but it works.

 

 

I have a powervision. I downloaded a Dynojet map for my engine configuration. It is a very good map. I think that Dynojet makes good maps. I did buy my powervision from Fuel Moto however, but I used a Dynojet map.

 

 

Fuel Moto!

 

 

Don't feel bad, mine is kind of the same way, although I did buy mine from Fuel Moto and used their map and have used the auto tune extensively. I just don't feel a huge difference. I do have the security of knowing my bike is tuned well.

 

 

FuelMoto is the best for service, I have my PV2 and have it on my second HD now, re-licensed it, new maps for free anytime you change things, simply email them and wait for greatness in your inbox. I won't go anywhere else ever.
