Ya I've just been meaning to take a caliper to it, but in all the times ive had that hood open i just haven't done it heh. reason i want to check is after my 180* thermo, DP, and HAI, i still seem to be getting quite a bit of KR according to my Scangauge. i Have powrtuner installed here on my laptop, but with school and work i havent had a chance to play around with it at all, and have been thinking of getting a pre-made one for the mean time.
