It will not fit.With the Akra base map and PCV on a '16 Duke, is there a significant benefit adding the runner? Will it fit?

This got me thinking what I can do for the duke guys. Stay tuned.So disappoint

This all takes place before the throttle body and into the airbox.Hello.
Just to be sure to understand...
The Intake runner you propose is the pipe between the throttle body to the airbox, right?
I agree that the KTM one is much smaller that the Throttle body diameter, so there is a useless restriction.
But what about the pipe inside the airbox? Do you remove it, replace it or keep it?
Thank you!
Hello.
I think a common mistake is to use piggy back ECU and modify the richness in closed loop area.
It could work great when we do it on Dyno. But for example if we add fuel everywhere, after real riding (stabilized condition, partial load) then the system will adapt and remove the fuel we added. So the improvement will be lost in time. Even worse, often, what is learnt by the system in closed loop condition is also applied in full load. So if you add fuel in closed loop area, you will loose fuel in full load.
I imagine this is what appened to you, Radar1075 : great advantage the first day on dyne... lost after few miles of riding...
By the way, do you know what is the closed loop condition on rc390?
Very glad to hear your experience went well. These respond exceptionally well so if you fuel controller can extend the rev limit out the more pull you will have. The larger injector will not cause any issues long term but if you install it and just expect the auto tune to sort it out it will take a while and run like hell.I purchased the custom box with new runner along with the injector. I have a 2017 rc390 with K&N filter, open lid, Leo Vince decat link pipe, Acro 2017 black carbon exhaust, and a fuel controller. My controller is less common (not pcv) so decided to install only intake because I was afraid replacing injector with larger would cause mapping issues. What I found is with new intake only, the bike is transformed. Expectations were exceeded. Bike pulls from 2500 to 7500 like never before in such a linear manner it feels effortless. One of the best mods I've done thus far. Problem is up top around 7500 to 8000 and up I feel no gain in power/torque. I'm assuming, based on an earlier comment made, that's due to stock injector maxing out. So the question is have, is if I install the larger injector, will that cause problems with my tune below which feels great? The auto-tune feature did an awesome job. First ride after install was noticeable but nothing to sing about. But by about 20 to 30 miles in, holy crap!!!! Just not sure if the same will happen with a larger injector since I'm assuming my fuel map was tuned using stock injector. Any insight would be greatly appreciated.
I went back to stock because it was going to take more effort to tune than I wanted to put in. It sounds like the fuel controller you have is a step above mine, so it might be easier for you.An earlier poster mentioned they tried and ended up going back to stock injector so am a bit hesitant.
Has anyone that received their intake had a chance to do a before and after Dyno? It's pretty mind boggling that such a simple mode would produce 20% more power over factory. Most turbo vehicles cant produce those results with a lot more than an intake and a reflash. Are these bikes just purposefully neutered from the factory like this, or was the 20% gain due to this mod coupled with the exhaust, higher compression, tune, ect.?
Its real, your result may vary slightly of course but say that you "only" got 10%. For a $169 bucks is that really a loss?Has anyone that received their intake had a chance to do a before and after Dyno?

Are you able to see the AFR while riding? I'd be curious to know what AFR values you get with the youtune module at various RPMs.
