Had the SERT installed and Dyno at the same time. Still popping some. Not as bad and very random when it does occur. The A/F looks good although the dyno didn't capture below 2400 RPM. I have a Heritage Classic, '06 with SE II slip ons and the Breather kit. No tach. Would an intake leak cause popping all the time? Or could it be random too. Just trying to figure out if there is something else going on. Will have them check for leak when I get it back in to them. They started with the map that called out in the software and did some changes in the VE tables. It is running cooler and popping less but still there and like I said very random. If this dealer can't get it right I am going to try to find another tuner. I live in Indianapolis and if anybody can endorse good tuner in the area in case I need a back up. What maps are others using for a setup like mine. I am getting frustrated with the whole thing.

 

If it is an occasional backfire, I would suspect you have an exhaust leak. Check all connections, head, mufflers, and crossover. Remove and reinstall your pipes with SE exhuast gaskets, new crossover gaskets, and clamps. Torque to factory spec.

 

Thanks Geo I will have them check that out when I get it in to them.
