RE: Stage 1?
These bikes run lean from the factory anyways. I'm sure it won't hurt anything. I did a full cobra exhaust upgrade with my HD stage 1 with no fuel management and it's fine.
Put on a stage 1 air cleaner (or verify that it already has one)and get it dyno'd (dyno checked not tuned.....there's a difference here)for your A/F ratios, get your baselineand then decide if you NEED fuel management. If you're consistently up in the 15:1 range or 16:1 range, then you're running way too lean and I would consider amodule.13.2:1 is the baseline under open throttle tests. If you're within 13.2-13.8 you're fine.'07 and '08 bikes will self adjust to keep the bike at the factory A/F ratio which is 14.7 during idle and cruisingso I would say fuel management isn't necessary. It's not the biggest bang for your buck (at least in my case). You're going to gain how much HP and torque? If you're planning on doing head work, cams, bore kits, well then you need more fuel buta SERT or PCIII, etcmay be overkill for a stage 1 upgrade.

RE: Stage 1?
Thank you all very much. The old owner just dropped on the pipes and nothing else. Also thanks for clearing up the IED (I just like to blow stuff up, sorry bout the comment Lucky...my bad). I will schedule a base line dyno and go from there. Hoping just an SE stage 1 intake will do but am hearing from local shops fuel management will be needed. Thought about the V&H fuel pak but seems to locked in for me. PC III or Race tune is the way I may have to go.
Thanks again to all for the help. I am sure you will be hearing more from me in the future.

RE: Stage 1?
No sooner did I write that statement that I went back in and edited it becauseIrealized the '04 doesn't have O2sensors so we would have to go in a different direction...that's the problem with buying a used bike, ya just don't know all of what has been doen unless the previous owner kept good records or is forth coming with the info at the point of sale...
