None of our products will automatically make any changes or corrections to address things like decel popping. This being said, all of our tuners have the ability to be used for custom tuning of the motorcycle... Meaning that the tunes can be opened into the appropriate software, to allow someone to make changes to the tune that can help.
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate the fuel. The absolute MOST common cause of decel popping is an exhaust leak. If there is a leak and it is not corrected, you may never be able to reduce or eliminate the popping.
To check for an exhaust leak, we would suggest that you get the bike up to normal operating temperature and then just let it idle. Take a lit cigar, cigarette, incense stick or anything else that smokes and run it along the entire exhaust, slowly. Allow the smoke to flow over the pipe, focusing on places where the headers are bolted to the cylinders, the oxygen sensor bungs, and any joints where the headers meet the mufflers, etc. If you see smoke get pulled INTO the exhaust, that would indicate a leak. Fix the leak and the popping may be gone entirely. If there is an exhaust leak, the popping may never be able to be solved with just tuning.
