I've read through this thread several times and still have a question regarding use of map 2, pc3, and aftermarket exhaust. Perhaps someone might be able to answer this for me? After making said switch to map 2 and using a pc3, is there a map or means by which to go to a temporary emissions friendly setting for emissions testing purposes w/o having to switch back to map1? My apologies if this has been answered elsewhere. I couldn't seem to find the answer whn using the search. Thx.
