FYI , Anyone who did the air box silencer/neckdown delete with the Colorado replacement K&N , you probably have a rich condition due to the air filter being bolted directly to the mass-air , there needs to be a short extension to smooth out the airflow before it hits the mass-air meter , Kirk from Vector told me my fuel trims would be skewed from this and he was right ,(filter was already on truck when I spoke to him), today my truck was at the dealer getting the service stabilitrack message checked out and my friend who's the head tech at the dealership pulled up a rich code from the ecm , so the benefit of removing the neckdown with the stock filter may be counteracted with a too rich fuel mixture not sure if I want to change it back to stock or leave it as is , even though with it being rich it's probably hurting power a little , hitting the track this weekend , maybe I'll bring the stock filter set up to the track with me and see if if makes a difference . We need the Vector CAI IMMEDIATELY !!!!!
