Thundermax issues
I recently installed a T-max w/autotune and some rinehart crossbacks on my 2008 SE springer. I've been running map 555 wich Zippers told me to run. So far I've lost 12 mpg ( getting approx 24mpg) Ive got frequent decel pop down shifting in the lower gears and the idle isn't constant. Anybody no what the hell i'm doin wrong? ive put 300 miles or so on since the mods were done.

That map is for Rinehart true duals and has a very rich fuel delivery.
Try map 413 which is for a Dyna with staggered duals.
Also load the base maps in the software and filter out all but 110" engines and try some of those maps.
Also post how the engine is configured.
