how to set thundermax timming

I have a 2007 FLHX with ness big sucker intake , fatcat with quiet baffles and thundermax with auto tune.motor is stock.my mileage sucks all around and doing rolll on's it ping's.the only time i get good fuel efficiency is when i ried to the high altitude.once back on the valley fuel efficiency goes down again.

Which map are you using? Did you modify the map? Did you try another map?

RE: how to set thundermax timming

i was using # 391 also i tried the rest for my application.a fellow team member from this forum posted a map for fatcats he altered.i download the map this morning and reinitialized the unit and everything else.it seems to be runniing a lot stronger now.the map was altered to run a bit more richer than stock 391 thruout the range.i believe is the extra fuel pump into the cylinder during acceleration that is making the different.no pinging at all an no decel pop either.hit the freeway at noon with temps aprox 70 or so degrees and did a roll on at 85 mph without pinging at all.overall i'm very happy and surprise how much a little gas will do.the team member's handle is Z_stingray.
