Short answer, yes you will.

It's best to add some style of fuel management with any intake or exhaust modifications but with a free flowing air kit it's a must.

I don't know if the 2009's have the same issues as the 2015's but Ivan's flash made me happy I bought a 1700. The drivability is vastly improved, vastly. The power comes on much faster and a bit smoother. It even runs a bit cooler.

I've owned several bikes over the past 40 years and the Voyager was the first one that wasn't fun to go rip thru the gears. Ivan's flash fixed that, cause it's a blast to go rip thru the gears now. It's no muscle bike but the sluggishness is gone and it'll happily hit red line with a normal twist of the throttle.

I recommend contacting Ivan or somebody with a 2009 see if the improvements are the same for all years. If I had to choose one or the other I'd take the flash because of all the issues it fixes.
This may make your decision more difficult but... There are 2 different flashs for the 1700's. One covers all stock bikes and bikes with slip-on exhaust and a high flow air filter (filter only NOT an air kit). Second one covers bikes with an air kit and either stock or aftermarket exhaust.

Lots of good info on Ivan's site. Ivan's Performance Products

thanks for the info - the thing that gives me caution is sending my ECU - how long did it take you? My bike is my main mode of transportation.

He flashes and ships the same day he receives your ECU. Shipping is what takes the longest, so it depends what you're willing to spend. IIRC mine took 4 or 5 days using UPS ground.

4-5 days each way, right?

I'm pretty sure it was 5 days total. Shipped on Monday, Ivan received/flashed/shipped on Wednesday, I received Friday. MI & NY not very far apart though.

what's cost-effective? Ivan's is double the cost of Chucksters BAK and that's what they recommend...
I have stock pipes (undrilled) and added Chucksters BAK and a Dobeck EJK. With the BAK installed and testing the EJK set in pass-through mode (essentially acting as if it weren't there) the bike ran way too lean and very poorly, so yes, you will need some sort of fuel manager with a BAK.

The flip side, the re-flash (or a fuel controller) can only add so much performance without a BAK due to the restricted OEM air flow. It will optimize the air/fuel ratio for the air that is available, and cool the engine some, but the benefits are limited and probably not worth the cost. Someone who has the re-flash on a stock bike will have to tell you if it is worthwhile or not. Racnray's throttle mode (I have that, too, but I sort of got it for free) would be a more cost effective mod for a stock bike, IMO.

Personally, I am very happy with the EJK. I got it before I heard about Ivan, and can't justify spending still more money on the re-flash. Knowing what I know now, I am not sure if I would pay the extra for the re-flash or not if I was starting from scratch. That said, I have not experienced the re-flash, so it may do more than I think it does for improving performance.
