get a real flash tuner! TTS/Powervision/SEPRT/(FP3 if '14 up) are flash tuners. Powervision is my choice but they all are only as good as the operator/installer/tuner. There are also good dyno guys out there who sell a license for a flash tune and you don't need to buy a tuner.

 

Checkout Fuel Moto for air intake and PV-2 tuners.

 

I did a stage one on my Limited this spring. De catted head pipe, K&N AC, CFR slip ons. I weighed the difference between a cheap tuner or a Power Vision 1. I decided to go with the PV1 because of the ability to auto tune and Fuel Moto's rep on providing good maps and customer service. A thousand miles later and I'm very happy with my setup and purchases. My bike runs much better and I've gotten a lot of nice comments regarding the low rumble and sound from the CFR's. The PV1 does a lot more than just tune and I'm still learning all of its abilities. Good luck on what ever you choose.

Cool thanks for the input. Im riding a 2011 Street Glide with the 103. Its all stock besides some cosmetic add ons and the screamin eagle fat shotz (which are too quiet for me by the way)

 

I had the Fat Shotz on a 2012 FLHTK with V&H Dresser Duals and it sounded great.
