    well I installed some LT's finally, and everything seems to be running right...
    but It smells really rich...
    my LTRMS at idle are sitting at -2 to -5 and my O2's are bouncing everywhere which I expect them to..
    my Ltrms at WOT are at +1 and the O2's sit around 902 -915...
    any advise here?

    If there are no cats on the truck its gonna smell rich with the LTs. slightly negative numbers are good for the trims, probably need to add some to the VE in the WOT range so you dont have positive numbers at WOT.
