Damn Chaz, so I shouldn't be popping even on deceleration down hills? I just picked up my tuner kit for my 07 NT from the dealer. I have a heavy breather and V&H Short staggered pipes. I should probably get the map checked, wish I had the cable to do it myself.

My 06 Standard popped like crazy on decel until I added a tiny bit of fuel to the 0% throttle columns of the Power Commander III USB Map I'm running,,,, along with Stage one D/L from the dealer and Screaming Eagle Hi Flow air cleaner with Vance & Hines BSS pipes.
I first checked for leaks as stated in the previous posts.
What worked for me was trial and error somewhat, adding a value to the 0% columns front and rear cylinder alike. I would enter a value then ride/test for decel popping,,,if it was still there I'd add a little more value/fuel. Going 2-3 values at a time. Once the decel popping went away, I would reduce the values by a factor of one at a time. Once the popping returned I would go up one value then I was good. I saved my map and for the last two and half years my bike just gurgles a bit on decel, mountains, hiway, town, doesn't matter. Gurgles. I ended up with a value of 5 (Again Both Cylinders) in the 500-1750 RPM Range---Then a value of 10 from 2000-4000 RPM Range. And this refers to the 0% THROTTLE COLUMNS ONLY,,,,so it didn't have any effect on my dyno tune.....I hope this helps.

 

Thanks for your help guys!

Im going to start playing with the setting tonight, see if I can get rid of some of the pops. Let ya know how it goes.


All the best,

Jack
