Last weekend I installed a Maxxfab 3" O2 Housing with their Hi-Flow Cat assembly...the install went well (with great workmanship andinstall instructions from them)but over the week I've noticed my UEGO doesn't read as steady as it used to, mainly at idle, but also if I'm cruising.Idlingconstantly changesfrom hi 13's to mid 15's (in .1 increments)where it used to sit right around 14.5 to 14.7, and fluctuate very little. At cruise say 70mph it bounces from 14 tomid 14.WOT reads like it always has. Can there be a correlation between the two or should I look for something else?
