This is kind of how I feel about it, for $50, what's the worst case scenario? I end up with a spare PCM that I can send off to get a real tune? I can't get a local tune because there is no one local, been there tried that. I started a thread in the regional section awhile ago and the nearest person that had any tuning software was in Kansas City (might have been Reptile, actually). I monitor KR constantly (it's built into my head unit on my stereo so it'll turn my music off and tell me that KR is occurring), so I figure if I get tons of KR, then I'll put the stock PCM back in, and go from there.
On a side note...I know you're not doing tunes any more Reptile, but if you ever want to tune a PCM for old times sake or something of the sort, keep me in mind. I've read nothing but great things about your tunes and I've wanted one for over a year now, lol. I was just flat broke back when you were still doing them.
