Stage 1 here. To me there are different levels of this too. Big difference between having open a/c and pipes, and having open a/c & pipes with a good tuner and a dyno tune.
Mine was dyno tuned with the SE Pro Super Tuner, which made my basic stage 1 a whole lot better....l like to call it a stage 1 1/2, lol
I'm going to replace my slip-ons with a pro pipe this winter, and may do cams at the same time, so then I will have a stage 2. I will never go any farther than that though. I won't do a big bore upgrade or ever have the heads done...gotta draw the line somewhere.
I enjoy the hell out of it now, so I may just do the pro pipe and be done.
The engine upgrades I have done are incredible. Many threads on this site have said this combination won't work. But I have a 09 FLHTCUI with SE Kompressor heads w/acr's, SE 103 flat top pistons, SE 255 cams, Stage 1 air filter and V&H slipon oval mufflers. No dyno numbers until next week but I will keep you posted.
