Just installed the Thundermax on my 2010 Roadglide, We gutted the cat out and you have to plug the stock 12mm O2 bungs and install new bungs 18mm 3" to 4" from head. Sounds much better and runs stronger. the auto tune seams to work great. Need to put some miles on it to get the AutoTune to adjust.
i have a 2011 road glide custom...i just installed my thundermax autotune and my d d exhaust. the problem i am having is that the bike pops a lot during decelarating on high gears 2nd and up....tried to follow step by step but i think i may have miss something.... also the download didnt have my pipe listed when they asked me to enter the model and brand. please help or pm me asap.....help !!!!!
Had my bungs welded in yesturday after I got the holes drilled etc, and rode all day with the pcv with auto tune today. The auto tune is changing my map all over and changed my map big time on the bottom and cruise range. I hope to see mpg in the 40s tomorrow. And to finish up with the auto tune making my bike a perfect map.
Well made it up to 44 mpg yesturday with the auto tune doing the tuning. With a fellow rider telling me on here to do some changes today to 14.1 vs the PC autotune stock set up of 13.7 af. Well see what happens know. I want mileage but still want power for passing so I give it a go on the way to work and back today.
