Snickers- I do have a couple of customers that may be interested when the time is right....You are right about the cats on the Porsche's though for sure, I figured there would be alot of gains because of how they have that set up. I have one customer that just did a re-flash and I drove it before and after...there was a difference, espically in the top end, but you could hear it sounded like it was being choked and there would be significant gains with a proper aftermarket exhaust. nice work, could you pm me an idea of what you think the price may be just so I can mention it, I won't hold you to it of course.
