Apparently I did, but it was only because I read the thread that said I could "drop it in" as a "maintenance item" before doing other mods... I am waiting until I get the downpipe and FWI installed (both sitting in my garage right now), then a seafoam clean, and 104 plugs. Then I will be hunting for a tune to get things working well, and later when I put on a PLOG and then a smaller pulley, I will get a tune again.
I can't find anyone near me that has a tuner, and I wasn't going to drive 2.5-3 hours to get a tune after putting in a 180* t-stat.
