Steve, I was in no way meaning my post to be a "kick in the nuts" at all. I believe that my issue has everything to do with atmosphere here compared to where you built the tune which is no fault of yours at all. As everyone knows every bike runs different and a tune developed for one bike may not work so well on a different bike all the way across the country, and to say it would is injustice to the consumer. I was in no way trolling to deface your product, but simply responding to another user who is experiencing the same problem that I had. In no way was that intended to be hostile. I to this day still recommend your set up to everyone who asks me what I recommend. I think you sell a great product at an amazing price and I'd without question use your products again. I don't have the calc number off hand but I'd gladly post it up tonight if you're wanting to know.
A good way to eliminate decel pop is to richen up the main lambda table in the leftmost (15%) column by about 10%, maybe more if needed, in the cells for the RPM range in which the decel pop is occurring. This puts enough gas in decel mode to prevent exhaust gas ignition in the pipe(s). With the Drago's S/C/S-4, I had to richen up my main lambda table by 15% from 1750 to 3500 RPM to eliminate the decel popping everywhere, since it scavenges so well. It's worked well on my bike.
This is a better approach than messing with the VE tables. It's very simple to do. I believe the TTS tuning guide says this.
You can also adjust the Decel Enleanment table to decrease the enleanment (i.e. richen the decel mixture), to accomplish essentially the same thing, but it is only effective for a short time... whereas the main lambda table is always effective even if you decel for several seconds or more.
