My question is has any car actually had ANY of these mods yet, and has the owner lived with it on the street for awhile?

You'd think if Renntech had done these mods in any way other than computer modeling, or one test mule rolling around, they'd be posting pix of converted cars, actually performance data, dyno charts for horsepower, testimonials and/or references.

Also, there's no way a test mule could've been on the road long enough to really determine the integrity of the mods from a reliability standpoint.

Even with the $1K chip, it looks like most folks are standing by and waiting for others to try it first in terms of actual performance gains, livability with the car, impact on reliability, impact on manufacturer warranty.

I'd love the car to have a little more grunt, and could spend a few bucks to do it (although I'd have some 'splaining to do to the wife for the Stage 3 upgrade), but I'm waiting for a few others to jump off the cliff first.
