I just deleted my PAIR system this weekend and have the 95-97 hard pipe ordered and I've already done the rear heater bypass and bypassed the EGR. My operating temp is down considerably from the minor mods I've done thus far, down to about 185 from nearly 200. Being relatively noobish to the 80 engine on my '94, this is first I've heard or read about simplifying the TB coolant lines. Can anyone comment about the benefit, other than the obvious, of deleting this portion? What's the purpose of the TB cooling lines? I live in the South, not 'that' cold in winter, but I'm all about eliminating unnecessary connections and potential leaks.
