Hello. Looking for some help. I recently purchased a 2006 Softail Heritage with EFI with 13k miles on it. Two days after purchase the fuel line went bad and the local dealer took care of it.

During that visit I had them do a stage 1 tune to it and I installed the screamin eagle stage 1 air filter assembly. The stealthy one that uses the factory cover. Ever since then I have had less torque just off idle. When takng off from stoplights I have to "blip" the throttle then release the clutch and accelerate or I get a pop through the throttle body.

Seems as if it is too lean at idle or a lack of torque just off idle. This has been worsened by the screamin eagle slip on catalyst mufflers I picked up and installed

Is this normal??

 

not normal, most people avoid cats. Did they do the hd download for the tune?

 

Additionally the bke seems to surge or jerk a lot at low engine speeds. Like 10-12 mph in first or 20 in second and 35 In 4th. To get stable speeds I need a lower gear and higher rpms.

Could be the fact I'm a ver new rider and this is my first bike but want to make sure. But seems as if third is too low and fourth is too high for in town cruising. Engine begs for another gear but lumbers and bike surges if I give it

 

Yes they did the HD download

 

Additionally the reason I went with Catalyst exhaust is this is my first ride. I wanted to get some additional breathing from the engine along with maintaining noise standards. I know there are most likely much better choices but I did not want loud... just better and maybe slight louder.

During my research, the catalyst ones I found were the only ones specific to the 2006 with EFI and that is due to the catalyst installed. So staying true to the stage 1 tune, I wanted to make sure I did not go lean and still maintained the extended warranty I purchased from the dealership.

 

Have you contacted the dealer about these issues ? If it backfires they may need to tweek the tune they did for you.

 

I have not contacted them yet as I just got the work done and not sure if it is my riding style (new rider here) or the tune itself. Just seems I need much more throttle than I used to prior to the fuel line failure and download they did. After I get moving, the bike definitely has more umph... it is just the off idle power and taking off from stop lights where I need more throttle to get going or it will "pop" through the throttle body and I smell a bit of gas

 

Sounds to me that something isn't right with the tune, especially if it is popping and you are smelling fuel. I would take it back to the dealer that did the work.

 

Turns out the intake is leaking. I'm starting to get concerned. 2 major issues in less than two weeks. Both fuel related. First the fuel line now intake. Grrrrrrrrr. Bout ready to trade her in or tell dealership to allow me to return it

 

Setting up a Harley to breathe more freely can do wonders for high end power, but often drops low end torque; you need some back pressure for that. Even tuned as good as can be, you can lose low end grunt with less restrictive mufflers. I've never had a used bike that didn't need some fixing, regardless of mileage. Come to think of it, some of the new ones did, too.
