Mine works pretty good. I put it on and let it tune itself and it made a huge difference in the performance of my Dyna. I installed a set of Andrews cams and left the same file in it and let it re-tune itself then had it dyno'ed 74 hp 83 tq out of an 06 Dyna 88" with everything else stock. No decel popping or popping when shifting.

No I haven't tried that. I assume I would have to put back the stock o2 sensors with the stock ecm module. When I changed out I didn't keep the sensors or wiring.

"r" Fuel Range no longer working after install
After I installed Thundermax on my 2010 Softail - the "r" fuel range indicator on the Speedo went south ... it now reads a ridiculously high number. I had read elsewhere (can't remember where) that Zippers had come up with a "firmware" upgrade. Their website says nothing ...
Has anyone else lost fuel range? Anyone know of a firmware upgrade?

Adjust the Fuel-Cut Off Points
Have you tried going into the software yourself and dropping the RPM point where fuel is cut off by T-Max? I had similar issue ... and I took note of the lowest RPM, i.e., about 1800 - 1900 where I got occassional but noticible pop and lowered the fuel cut off to 1750. I then lowered the upper RPM fuel-cut off point from 2400 to 2250 ... just so the system would not be dry/fuel starved for too long. Most of my decel pops are gone now ... though I do get an occassional pop at low end ...
I've seen other guys try and resolve similar issues (pops and pings) with a couple of Dyno runs and "expert" tuners and most are never really pleased ... I've done better tweaking the T-Max myself .. at least I know what I did and why I did it .. and I can undo it. Crux of the problem is that you and the bike form a unique operating environment and the Dyno and tuner/expert can't re-create that environment ... best of luck.

yep, my comments are in that post...I had a bad taste with TM....I guess the biggest thing is there is noone to diagnose any issues...if you can't figure out the issues on your own...no dealer/indy is gonna touch it...at least in my area.... your mileage my vary though...
