I put a Speed Merchant on mine at first (no air filter upgrade) and a remap was 100% necessary. I got a quote from the dealer for $200 some odd dollars for a stage 1 remap. I think $260!!! I told them that was crazy, got an FP3 for maybe $315 on Amazon and used the Auto-tune function (I'm in CA so there are no maps to download). For the extra dollars I think it is worth it to get the ability to make my own maps based on my bike and how I ride. If I change anything in future I know that I can tune her myself and get in there and tweak anything and everything just the way I want it!
Have to agree here. While it "pairs" to only a single bike (and many say that's a negative), having the ability to use multiple maps with that single bike is a HUGE advantage.
As an example, I used the base map on mine and was "auto tuning" a map. Well at one point I had 52 TPS cells learned and went to apply them. Something happened and ALL the data erased during the transfer that never completed. If you have used the auto tune before then you know how "hard it was" to learn 52 cells, and what kind of riding that entails at both ends of the RPM spectrum lol. Needless to say I was pissed. At any rate, while "continuing to auto tune" my MPG dipped really low (like fuel light on at 80 miles) and the bike began acting a little off. So I added another map then remapped it BACK to a non-custom (non-auto tune) map and "everything cleared up" perfectly. Back to tip top performance, back to 120 miles before the fuel light comes on, and back normal.
This was a huge benefit for me. Being this is the 1st time I used an FP3 on my bike there is a learning period but you can do that with this. At any time you can make changes, revert to other maps, or install custom maps if you are into that. Plus if you wanted to see all the details about the engine during riding, you could mount a phone to the bike and see all the mechanical details in real-time when driving.
Just my thoughts but do your own proper research so YOU will be happy with the decisions and choices that YOU end up making and that YOU have to live with.
Also, to me, just put in the V&H naked air intake (hi flow) and through on a Fireabrand Cannon at the same time and use the FP3 to tune it; you will NOT be disappointed. The add-on's are all preference but after doing about 3 weeks worth of research and discovery, this was the setup that I thought was the best possible for total cost outlay.
PS - if anyone wants to buy, or needs to buy, the "Chrome Cover" for the V&H Naked 02 intake let me know. I bought it for my bike and realized it was CHROME after I opened it lol. I never used it at all as I used the one in the kin and bought the black one I wanted. It's for sale and you save a bunch of money off NEW. They charge a crazy $60-$75 just for the cover so here is a chance to get one for much much less.
Best,
