Well u may consider a private shop to do the pcIII and dyno tune. However, I think if the hd dealer does it, it don't void ur warrenty.
The se tuner is decent but I wouldn't say its the best. Hv u checked arnd more? Try some hd forums? I'm also on
www.aimag.com forum and there is lots of info on thr abt tuners.
Also check out night riders site. He has lots of tech docs and a nice forum u can search. Can't wait for the inline xieds are available for the 09 flh's. They get u cooler motor and slighty better response by simply fooling the O2 sensor into telling the ecm to put in more gas to richen up the super lean epa mix they hv to hv from moco.
I'd link ya some stuff but posting on phone as I'm out in pa for the rally.
Later!
