I am wanting to install a thunderheader on my 08 FXD.I am also installing a couple of Nightrider o2 IED's..stock aircleaner
My question is will it hurt for my bike if I donnot get a map download,or install a Power commander..I know I will sacrafice some HP
I am mainly wanting to keep my O2 sensors.I feel they have a purpose.....

 

I thought in your earlier post, you stated that you had a PCIII??????

 

I did have a PC3,but thought maybe it was having a conlick with my ECM..So I decide I was not wanting to use a PC3,as you have to use O2 eliminaters..
Since I hope that my bike is Ok now,I will rehash the idea of putting the PC3 back in.This deal about the trouble lights and bike quitting,made me like my stock stuff for awhile longer..
Thanks for the reply
I can really use the advise
I am heading for the All Harleydrags at midamerica in East St Louis tommarow(450 miles one way)..So now we see how the FXD does.
