Ok fellas here is what I got stock motor was a 96 I put 103 pistons and jugs on it with s&s ez-551 cams opened up the back plate and added a fp3 over two years ago only to find out v&h never added the cams to my map. So now that I can I went in and added the cams and the bike runs terrible way too rich raw fuel coming out of the pipes. I called v&h last night and had to have them put my stock cams back into the map they blamed it on my exhaust stock head pipe no cat double slash mufflers. In my opinion I now looks like a lack of air gonna remove air cleaner tonight and retry a map with the cams in it.

Whether or not you pick up anything depends on how well the intake tract flow as a whole and that you exhaust system don't choke things off. If the inlet to the throttle body has a squared lip, it might be worthwhile to find and AC that has a more rounded entrance. Still it depends on how good the rest of the tract is. Exhaust system also but it becomes more important when you move away from stock smogged cams.

It appears there is something wrong with your tune.... I would now be suspicious of the original tune, without the cams. Really lean tunes tend to run well, seat of the pants....
The FP3 is great for adjusting for a stage I, but there is a reason that no reputable tuners use it for their builds/dyno tunes......
You did some major mods, I would have gone right to a TTS or PowerVision for your tuning. But hindsight is 20/20......
I would get a proper dyno tune if there is a competent dyno tuner near you... if not, at least call FuelMoto and see if they can fix you up with a PowerVision and a tune...
Good luck sorting it out....

Yep I am now thinking of new tuner when I got the fp3 a few years ago it worked seemed to work fine but now I'm starting to question it and v&h they had no answers or suggestions at all
