Hi

Have 2009 Heritage. Have put on the Screaming Eagle free flow air filter and the dealer did the download. I now want to put on Vane and Hines slip on longshots. Do I need to add a power commander and/or fuelpak? Or am I good to go with just the filter and Download.

Cheers

The download that your dealer put in may be suitable. Having both a free flow air filter and open pipes will make the bike go a lot better but may suffer from heat etc. You will know as soon as you ride it as it will back fire etc on decel. And you may get heat issues due to the lean mixture If it does then the map they loaded was to lean. If you can scrape together cash get the TTS. The others are ok but just a piggy back system that sits under your seat somewhere. Plenty of help on here for anything you eventually get. If you do have back firing when riding don't ride it for too long like that as you can do some damage to the engine. Even going back to get another map loaded will in the short term solve the problems..

Had the Thundermax with Autotune for about 2yrs now on my 2010 Fatboy Lo, it has run great from the first day I installed it on my bike.

No Decel, No backfire it runs sweet
