No you don't. The fuel injection system via the oxygen sensors will compensate for the added airflow. It will run the same EPA compliant lean map.
Now you will WANT to add some form of enricher simply to keep the head temps a bit lower but you don't NEED to.
The popping is going to be an exhaust gasket issue. The dealer downloaded stage 1 is a waste of money. It is still EPA compliant and lean. If you don't plan on any other mods xied's will work well for your needs.
Now if you are planning cams or anything internal down the road get a real tuner. The pcv gets good reviews as does the power vision and thundermax. And either of these options leave you with the auto tune option.
Don't waste your money on a fuel pak. The popping doesn't go away with it. I am tossing mine in the trash. By the time you email the company 50 times and they get you to change this or that,and the decel pop is still there or the throttle backfire presents itself,you waste ride time and the constant screwing around. The fuel pak sucks. Dealer download is useless too.

 

The Power Commander will over-ride the Dealer's Stage I flash if he does have it. You are right though, a tune would be his best option (as I stated earlier). Find a trusted tune center and get it diagnosed there. The Power Commander will do no harm, and will most likely give him some improvement over his current situation if not remedy the situation by giving his bike the correct air/fuel ratio according to his newly added performance mods. Hard to tell without seeing the bike, but it does sound like an improper air/fuel ratio is occurring here. Pretty probable the shop he decides to take it to will correct the air/fuel ratio by means of some sort of EFI tuner, the Power Commander is a pretty common choice (one of the better ones in our humble opinion), but just like everything else, choose the option that best suits you.

Ok, I guess I have to retract that statement. That is one of those dangerous "always", "never", or "best" phrases that should be avoided. We are big fans of Dyno-Jet and it doesn't take much research to see their very successful track record and experience with tuning and performance. They are one of the top producers of EFI tuners on the market today. That may change in the future, but for now, they are a pretty good choice. We are an authorized dealer of quite a few different tuners out there, and have experience with a handful of them, the Dyno-Jet products have always worked well for us. The bottom line here is the 'custom tunes' these and other systems like these provide. That said, the modules are only as good as the dyno-tech or tuner doing the tuning, which is why Dyno-Jet holds trainings and ongoing education on the whole process. A certified dyno technician goes through a rigorous training program in order to be certified and must stay up with their continuing education to stay on top of the technology being introduced. I don't know if any of the other companies out there are as thorough with this whole process. it is for this and many other reasons that we choose to primarily use Dyno-Jet products. Our apologies for getting excited and making the statement about Dyno-Jet. We don't mean to offend anyone and believe in having choices among the many good products out there.
Enjoy the Ride.

 

I always thought the poping was unburned gases in the hot exhaust igniting?

 

Bozo,

I have a stock 2012 RKC with 4" Rineharts. I purchased the Power Vision Tuner and Stage 1 air cleaner from Fuel Moto. They installed a map for my setup and my bike runs perfect. I've had both Power Commanders and ThunderMax tuners, but the Power Vision is the easiest way to get your bike running correctly. The Power Vison doesn't piggyback your ECM. It will save your stock map, and then write the Fuel Moto map to your ECM. Unplug the PV and you're on your way. I would agree with those who say that canned maps are not as good as a dyno run, but the folks at Fuel Moto know what they're doing, and their maps are excellent. Call them and they will take care of you.

Man, there is a lot of misinformation on this thread.

bozo, if a dealer did the Stage 1 download go back and tell them what is happening because apparently they did not do it or did it wrong.

Shreding rubber is incorrect. The O2 sensors will not compensate enough for your air intake and exhaust mods. You need the Stage 1 download with your mods. And it WILL work. It worked on my bike with a SEAC and SE muffs, and it still works with the same except 2-1 Thunderheader in place of the stock exhaust headers and SE mufflers.

Yes you can spend more money for an aftermarket tuner and get good results but unless and until you will be doing more mods, you don't need it.

Good luck and ride safe. Watch out for people turning left coming your way. Bikers where I live are being killed almost daily by left turners who say they did not see the motorcycle coming.

 

Frog,
Thank you for those comments, very well said. Those are exactly our sentiments, I guess with the shortness of the reply those ideas did not come across as intended. We want people to seek out good information among some of the bad information out there. We continually turn away money from potential customers as we seek to inform them and not just sell them what they think they want at the time (part of the reason why we are here on this forum). You are correct that he should seek out the advice of a trusted professional, that is the first reply I stated on this thread. That being said, it is highly likely that in one way or another he will be in need of correcting his upset air/fuel ratio. The Power Commander is an option for correcting this. It may or may not fix his problem (our money is on it helping the situation though!), but he will then have the ability to tune his bike according to whatever modifications he already has or is planning on doing in the future. Harley-Davidson modifications are highly prevalent because of enthusiasts like you, me, and everyone else on these forums. If we weren't interested in these topics, we wouldn't be here talking about them.
If he did come to us asking to fix his problem, we would not sell him a power commander as the solution. It may end up being part of the solution, but if his problem is with a loose exhaust manifold, or a stuck compression release, or any one of 100's of possible issues, than the power commander wouldn't be the logical choice for his solution, but would be a good choice if he is looking to tune his bike after the problem had been fixed. One way or another, he added an exhaust, is unsure of the condition of his ECU, so he will most definitely need to adjust his air/fuel ratio by some means.
Sorry if my message came across wrong, that was not my intention. You have some valid points that I am in complete agreement with.
Thank you again for your comments and concerns with this thread. You have definitely given the people reading this some good food for thought.

 

WOW, all this is overwhelming!!!! Thanks Mr Strider, the dealer that installed the download basicly told me I was riding at too low an RPM. Called another dealer and he said that was possible. Have only been about 75 miles on new stuff so maybe just don't have a good feel yet. I have riden most of 40 years but I do have a tendency to lug the motor down when in town. thank you

 

When you install True Duals and slipon's with 2 inch baffles, you will lose some low end torque. If you are going to cruise at 30 MPH, gear down so you won't lug your engine. I know RK's don't have a Tach on them. I listen to my engine. I use a simple rule when cruising. 1st gear to start from stop. 2nd to about 30 MPH. 3rd to about 40 MPH. 4th to about 50 MPH. 5th to about 60 to 65 unless I'm going up hill. On level ground riding solo, I can use 6th after 60 MPH. You will be ok with the Dealer DL. I ran stage 1 with Dealer DL for years on bikes. I would only buy a tuner for big bore and cams. JMO
