Hmmm....
From the looks of it, this Stage 1 thing might really be a crap shoot...from purchase all the way through installation. I dunno, but although it seems well worth the money if it WORKED...there's way too much room for a major SNAFU along the way...[xx(] And when you have a brand new otherwise FULLY WARRANTIED car to consider the risks might definitely outweigh the benefits...
Anymore insight?
