is there a programmer that will help out since i cut the cats out of my truck that will make the rear o2 sensors not work or anything like that or is there something i can do to make them work right because i removed my cats and had awesome power and then just felt sluggish the second day i had them taken off.. ans im not putting them back on because i am about to install a cam

 

SCT tuner, you'll need it anyway to tame the cam unless you're going to piggyback it. You could always do the non-foulers for the rear 02's, but you might as well get in touch with Marty at KRC and kill two birds with one stone...
