I recently installed the following item on my 2016 Road Glide Special. Generic 2 to 1 exhaust, Arlen Ness Monster Sucker air cleaner and a V&H FP3 Fuel pack. Having followed the directions and watched a few videos the bike is running. Seems to be a bit quicker than when it was stock. My question is I get a burbling and sometimes a miss fire at cursing speeds. Is this normal? I am running the generic flash in the FP3. Curious to see what happens if I switch it to the Hi Output stainless V&H 2 to 1 Flash.............And advice great welcome , excep for trash it all and start over LOL

 

try running about 3 tanks of gas through the bike- the ecm will make continual changes.

if at that point you think you have driveability issues, try autotuning

I'd draw a parallel to getting a new glasses rx- the glasses do so much, but your eye has to adjust to it...and that takes a couple of days

 

Mike is correct ride the Bike for awhile, the same goes for the auto tune, it will take
time for the ECM to adjust. If it still not running right, then you need time on a dyno
to tune some of the problems out and have it properly mapped.

I love the notion that somehow the ecm will magically change it's tune/map. It just ain't true. If you have a drivability problem with the current tune/map you or someone needs to change it. Might want to call V&H...

 

Like already suggested, run a couple of tanks of gas and see what happens......If your not happy with that, run the auto tune using the FP3.....If your not familiar with the auto tune.....Lots of information on the forum how to....

 

I run a 2 into one, Not V&H, on mine, loaded the V&H pro pipe , and it runs pretty good, Probably best to contact them for closest map

 

I agree, poor tune

 

"Burbling and misfire"?? You mean popping and perhaps backfire? Did you replace the exhaust gaskets when swapping the 2 into 1? or perhaps the headpipe just isn't tight enough?
