CFR slip-ons and PCV map
I finally found a set of used CFR slip-ons in great condition. They're not easy to find to say the least.
I should receive them early next week. I currently have Rinehart slip-ons on my 2009 Ultra with the stock headers, a SEAC and PC-V.
Will the map for the Rineharts work equally well with the CFRs? They're 4" vs. 3.25" for the Rineharts so I guess the airflow and back pressure will be different.
I don't think I'll find a specific PC-V map for these slip-ons unless someone running them made one. Is there a map for similar 4" slip-ons available?
I would prefer not to have to dyno the bike to get one because of cost. I'm not looking at the most perfect map here, just an adequate one out of the box.

First of all congrats on finding the cfr's.I'm sure you can try and see if you'll have a problem with your present map.If you got the pcv from fuelmoto just call them and they'll send you a new map.Either way when i first got my cfr's(slipons)i only had the stage1 and heavey breather and all was well except a little stumbling.When i got the cfr headers i got the pcv from fuelmoto and everything is great.Never dynoed. Supposedly the cfr's are difficult to dyno tune due to their openess.

If you use the auto tune with the PCV you air fuel ratio should stay the same and not go way out of range till you can dyno it.
I used the map that Fuelmoto gave me on mine and could not be happier.
I have monster ovals though and they had dyno tuned bikes with my exact setup.
I think if you did not buy from Fuelmoto you should be able to contact powercommander and get a map from them to get you started.

I have CFR's on my 08 SG love the look and the sound .I did have a problem with decel popping I had it dyna tuned it helped but the mechanic said it's hard to tune them because of the lack of back pressure. I have since been told CFR has it's own fuel sytem that works better . This winter when I get some head work done I will look into a different fuel management system because I do think they have the best sound of any pipes out there.

If I experience too much popping, I'll ask my mechanic who knows his sh*t when it comes to tuning HDs and I'm pretty sure he'll advise me against dumping my PCV. If I need to increase back pressure, I'll put torque cones or Monster Baffles at the end of the head pipes and that should do the trick.

I want to get new slip-ons. I have the Rush 2.25 and they just arent loud enough for me. Also my packing is blown out of them at 1000 miles. Rush is gonna have reps at Delmarva bike week. Im gonna tell them what I think of their slip-ons. Theres no way the packing should have burned out at 1000 miles.
