With the wicked curves pipes from LA Choppers you will need a fuel management system. Several of us had our bikes tested for AFR years ago and these pipes will make the bike run an unacceptable AFR.Just get the PCV and use one of the 4 maps I posted or one of the maps that others posted. Check out the recent discussion on the cobra power pro as to why its not proven for these short pipes as well. Shorter pipes require greater flexibility from a tuner. The PCV gives you that. When you get a BAK just switch your map. If you like the map keep it and save your tuning dollars for something else. If you don't get a personalized tune. The pipes are awesome BTW. Not sure why you're getting the BCT baffles though. THey are nice but expensive considering that the newest version of the Wicked curves will have the baffle packing so you won't have the chirp and will have a lower tone. Personally, I'd skip the BCT baffles as well to save cash..
