Rocker stage 1

I have Vance and Hines Big Radius pipes on the way along with Big City Thunder baffles and a SE Heavy Breather intake.My question is if everyone is going with a tune or fuelpak on this setup?I have been told by a couple of different people that on the 2008's with O2 sensors, that it is possible to not need either option. I was advised that I could try and run it without and see if I have problems with popping and hiccuping and if problems arrise, then add the tune or fuelpak.Can anyharm be done by trying this?Is anyone running a similar setup with sucess?What are your thoughts?Thanks!

I used a fuel pak with my heritage with V&amp\\;H pipes and K&amp\\;N filter set up. It worked well but when the XiED from nightrider.com came out I bought and installed a set and they helped cool the bike dramatically. Fuel pak works during open loop for the 07, 08 bikes which is 50% to full throttle. The XiED or IED works during closed loop which is from idle to 50% throttle.&nbsp\\;No more high heat at stoplights.

I don't believe that is true. I went with the SERT. People go back and forth with their opinion and I'm sure they are all great in their own way, but my dealer was more comfortable with the SERT so I went with their recommendation.

I put Big Radius pipes on my Rocker along with the 103in stage 2 kit and the bike runs great.&nbsp\\; I had HD do their download for the 103 kit and then put the pipes on myself and have had no problems.&nbsp\\; I just cut the baffles in 1/2 and the bike sounds awesome.&nbsp\\; Good luck

RE: Rocker stage 1

I have also heard that the '08's ECM are able to self adjust, but I don't know how much they can adapt or if this is even true.
&nbsp\\;
Does anyone have the definitive answer to this?&nbsp\\; I'm sure that if it can adapt, the aftermarket suppliers wouldn't be too happy.
&nbsp\\;
I've done a lot of reading on ECM's and think I am leaning toward the Thundermax.&nbsp\\; It has the ability to adjust to&nbsp\\;whatever setup you have (pipes, AC, cams, etc) plus it can adjust for whatever riding conditions (temperature, elevation etc) you have.&nbsp\\; It costs a lot more than the others (SERT, fuelpac, PCIII etc.)&nbsp\\; but does not need dyno tuning no matter how many times you change your setup.&nbsp\\; Change your&nbsp\\;setup more than once and it pays for itself.&nbsp\\;
