anybody..biggity bump

 

well I think that you meen NO readings because there is no NO2 reading. If your NO reading is that high you only have 2 options. 1. hope that a new Cat and retarding you timing 2 deg. will get it down. but unfortunetly not likely. and 2. but back in your stock cams. Most likely this is what you will need to do. What is happening is your cams are causing more heat to be generated in your cylindars which will bring up your NO Level, and your cat is what will clean this up. With a new cat it might bring the numbers down and by retarding the timing it will help cool the cylindars down and also bring down your numbers. Unfortunetly with how high your numbers are I don't think you will be able to bring it down enough sorry.

 

i might be getting 403 cams as well and would like to know this..
