Quick question.
Getting a bit of decel pop. Not a lot but now and then.
Been told by some too much and told by others not enough fuel

Do I increase or decrease the fuel....

2 into 1 pipes, stage 2 filter, and programer that was tuned by harly shop when it was dynoed....

 

Add fuel at throttle closing if the tuner can do that. If you aren't running baffles, I suggest you put something in your pipe.

 

Either one will work, just got to get the fuel/air mixture wrong enough to not easily ignite in the pipes.
Don't mind decel pop myself. It might have kept a cage or two from changing lanes into me.

 

The worse popping I ever had was when I had the dealership install all the Stg1 stuff with the SERT and Dyno at the 1k service..

The wrench didn't get the Slip ons clamps mounted right and I had an air leak at 3 of the 4 slots on both pipes, total of 6 of 8,,

They retuned it twice, no better, then I called Rush after they said its probably the muffs.

Less than 3 mins talking to the Tech at Rush and we had it figured out.

Back to dealer, Removed and install again with new clamps
Retuned again and ended up with at least 95% gone..
Now all I get is a gurgle once in a while.
