Here's two charts for consideration. The six gear chart might not be exact for all touring bikes. But it's very close. The other is from the SE catalog. Most riding is done at rpm's between 2000 and 3500. I am refering to most touring bikes two up. That being said the SE255 will deliver lots of torque for tight low speed manuvering and plenty left over for cruising 70-80mph in 5th and 6th gear. The SE204 performs similar. Both charts assume properly tuned engines.

Great graph Bingee. Even with an SE255 cam, it serves to demonstrate that we should spend more time in the upper rev range! After all we are not driving turbo diesel multis, with dual mass flywheels.

It's just a matter of dollars. For $2,000 you can get a SE 103 Stage IV kit and stay within the warranty. Here's that chart.

I know there is a search feature but the possibilites are endless.
I have a 2012 Street Glide with RC headers, Arlen Ness Big Sucker and wild pig slip ons. I have a PC 5 and right now I believe my tune is out of whack.
We rode to and around the Ozark mountians this last week and my surge is really bad in 4th, 5th and 6th gears if I go 1/4 to 1/2 throttle and try to roll into the power. If I go WOT it pulls but sounds like an old carb car with the breather flipped over. I have checked everything suggested and come up with nothing left to check except the tune.
My fuel mileage is way down and a stock 2014 SG was way better economy and pulled hills in taller gear than me. My right rear slip on is seriously discolored where it meets the head pipe.
I called Fuel Moto today and ordered a Auto tune and they are sending me a new base line map to see if that helps but I am serioulsy considering a different build.
My style of riding is often 2 up on flat lands (Seal level) but also tour around different parts of the country. I am not looking to pull the front wheels, but I would serioulsy like some more grunt from around 2200 RPMs and up. I dont often blast to the rev limiter but I also do not want a bike that pulls really hard to 4000 and falls on it face either.
Anyways after all of these issues I have been serioulsy considering a big bore of some sort. I like the Fuel Moto 107 kit, but I am not sure if I need that and if I choose that do I want the TW 222 cams or the TW 555 cams?
Or do I just want the cams and go from there? Or should I look at another supplyer? Is the 103 to 107 build worht it?
OK I know, Lots of info in this post but I am hoping someone can point me in the right direction.

Just wondering if your current tune ever was spot on? I was having issues with my stage one 96" years ago that was running a PCV and fuel moto map. Ran great for a couple years and then it started acting up and not running as well. Everyone recommended disconnecting the PCV completely and taking a spin to see if the issues went away. Well I did and they did, I just had a PCV go bad. Bought and installed a new one from Fuel moto and it was back to normal.
Its easy to remove your PCV, try taking it off and going on a short spin around the block and see how the bike runs. Its a free test to eliminate the chance that it might be a bad unit.

Well right now I think I have decided on cams, head wok and a good tune. I am talking with a guy local to me who is also on here. He was sharing some of his numbers and it is apparent there is a lot of gains to be made in the 103. He has recommended Ed in Dallas to tune it once the build is done.
All I know is this thing is anemic as it sits and I am very disappointed in it right now. I will throw whatever I need to at it to make it perform.
