I've taken my bike to the dealer with the xieds on and they never said anything about them.
Do you "need" a tuner? No. There's plenty of people on here and other places that have a tuner and have had their bike professionally tuned on a dyno and they still have decel pop. So there is no guarantee that having a tuner and having your bike professionally tuned on a dyno will get rid of the decel pop.

The fuelpak works in open loop and the xieds work in closed loop as far as the fuel goes. I told vance & hines I have xieds and they said there wasn't any adjustments needed to their settings on my current map for my fuelpak. Even vance & hines has said that they work very well together. I know my bike runs great with both on there. If you are like me and don't plan on any internal engine work I think they are a good/cheaper option to spends close to a grand on a tuner and having the bike dyno tuned.

I know you are satisfied with your setup (and based upon this forum are in the minority) but for someone who is starting from scratch I believe a good tuner such as the Powervision offers maximum flexibility for the future.

I have $625. total invested in my tuner and dyno time. (me and my brother split the cost of a TTS 2 bike tuner and it was 300 bucks for the tune. I plan on keeping the bike, so to me it was very little cost to have the bike permantly reflashed and done with no fussing around.
I didn't do it to squeeze a little extra horsepower and torque, I did it so my bike would run the best it could.
Your bike, you decide. For me, it was a no brainer.
For all of you that know you are done with engine mods...You can use your dyno tuners tuner by paying a license fee and pay for a dyno tune without buying a tuner and be into the whole thing for about $450.

I have had Power Commanders, Serts, etc. on my bikes, and haven't been happy with any of them. I was fed up with the whole thing. When I bought my latest bike, an FXDC, I swore I was gonna keep it simple. I did a stage one with SE air box, Vance and Hines Twin Slash slipons, and dealer download. My bike runs GREAT! No backfires, popping on decel.....nothing. My bike runs cooler, and the plugs look fine, according to my mechanic. I know, I know, the dealer download is a waste of money....yada,yada......I've heard that a million times. I, frankly, don't believe it. All I can say is it works better for me than all the $1,000 tuners and dyno runs did! I'm definitely a fan of the simple download for just a stage one.

It's not as much the tuner as it is the clown that sets it up. There are alot of people that have spent a lot of money and still don't have it right. The "download" works for a small percentage and that's great, but what if it doesn't? Then more money is spent making it right.
I've never understood the "auto tune" If it was really auto tune you wouldn't have to fu around with it so much.
Everybodies different, every bike is different. You have to figure out what's best for your bike by doing your own research and taking all of our advise with a grain of salt.
The only thing about having it dyno'ld...you better know who's tuning your bike before you take in your bike or it could be a total waste of money.

I have a very good independent shop that I and other friends have used. When I went there a year ago to talk to them about getting my bike with V and H slip-ons and Screaming Eagle Air Cleaner dyno'd and they told me not to waste my money ($700 for the license fee and dyno tune) unless I was ready to go with the full 2 into 1 exhaust system and cam replacements. He said I would be back anyway so why not just wait until I was ready to do the whole magilla.
Thus I am where I am. Riding with just the slip-ons and the stock air cleaner. I took the XIED's off yesterday to see if the intermittent low level pop at idle went away. It did not. Now just thinking about putting the hi flow air cleaner on and telling them to dyno it. I am sure I will be happy for a long time.
