I have a 2006 700 efi .. I put the muzzy exhaust system on it and bought the fuel programmer , anyone else running one ?

 

Am i the only one running a programmer ?

 

guess so...i had a copperhead,but got rid of it.

 

how did you find the copperhead work for ya ?

 

Not a whole lot of extra power. I could hardly tell. Better throttle response from a dead stop,not such a big hesitation though. You really need to get the interface,and the m109 injector to use the copperhead. my main reason i got rid of it is that it didnt work at 7,000ft. i live at 500 ft and it was fine but the bike died all the time at 7,000 plus. Called Lyle about it and he said it doesnt read pressure or something like that. So i threw the stock back in and ive never had a problem. 400.00 wasn't worth it to me.
