will i need to jet differently on my viper with aaen pipes and a peak head with 22cc domes, i also have my dash drilled with many holes and have my left ram air vent dropping air into my airbox directly, should i start at about 165 mains and about 3.5 needle and pilots ??.
im running at sea level and i would like to be safe until around -10. any input would be great.
 

yep, you changed all those things, it will change the jetting, start off with reccomended jetting for the pipes and go from there letting the piston wash and plug color guide you as to the jetting sizes.
