The springer was recently retuned to try to lower the oil temps ,and they got them down 20 degrees but now have lots of popping when I let off throttle  ?

 It's in the tuning!! They can get rid of that if they tune it right!!

 Some will say it's lean and some will say it's rich on decel, but either way, they can tune that out. Most good tuners would automatically tune it out, but sometimes they can miss it I suppose!!

 Talk to your tuner, he should be able to fix it!!

Check the header pipe bolts to see if they are loose on the cylinder.  Also check the pipes for any small holes or leaks.  It is often one or the other and both are simple to fix.

My experience has been too lean. Add a little fuel and a little timing  in the 0% column  from  1500 RPM on down the  bottom fo the column   this will  get the fire back in the hole where it belongs>>> Tru Duals tend to lean out the back hole a litle more     Greg

skipy, you running centerfold pipes by chance?

[Mikey]

True duals seem to add to the problem!

Tuning or air getting into the mufflers. Check all bolts(flange, clamps etc), feel to see if you can feel an exhaust leak first. If thats not the problem, need to get it tuned more carefully, specially if you are running a sert.

Check that cross over pipe and the joint where the slip-on's connect to the headers.  If everything looks good and snug then add some more fuel via Power Commander, etc.

"Decel enleanment" spec

The map leans out the mix on decel based on a variety of parameters.

With a SERT you can minimize the enleanment value to all zeros, which will solve about 99% of the decel pop.

Can you do that with a PCIII?

the old saying, starve it or feed it. with pc3, go to your 0 percent table and take out about 4 points . if that doesnt help, go back and add about 4 above where ya started.

still havnt seen what pipes you got?

Freedom true duals with their cams and gear drives etc. Their map on the PCIII.

i am wrong at times, so take this with a grain of salt. what i see with true duals is they all have big reversion. think hot unburned air/fuel colliding with fresh cool air. popping! in the case of duals, i would kill fuel under idle rpm s when you shut throttle, there is less unburned fuel in the long pipe. and hopefully no afterburn (popping). you may also add a little timing to idle--be careful.

Give Brad at freedom a call and tell him what you are experiencing he will take care of you.

Mikey,

Just played with this today with the power commander 3 usb.   I talked to some people about this and got mixed answers some say add fuel some say take away fuel ....  In my case adding fuel didnt work.   so in the 0 column  from 1500 rpm down I took away fuel ie -20 to all the column below 1500 and no more popping with the rineharts.   I will now go back and figure out what the right number needs to be, but I was using a crude method to figure out whether I needed to add fuel or take it away.
