mille has developed abit of a missfire,only really noticed it when i changed from stubby can to twin high level cans,
it has previously been chipped for the open airbox and stubby can,would changing the end cans affect the fueling enough to missfire,
its only really when i crack it open seams to splutter abit before it clears itself and lifts,not all the time but quite alot if that makes any sence,
i think its an eprom chip the now.
 
Defo sound like a fueling prob m8 ,are the high levels renegades as rsv ecosse has them on his it might be worthwhile asking wot chip he's using....
 
na there giannelli cans they split into 2 peice from origonal single down pipe,
 
Yes it will need to be retuned due to the different back pressures changes .. Put a Mivv GP pipe on my 03 & wouldn't rev out past 6000rpm without miss firing & made no power anywhere , have it hanging on the shelf now
