I did the mod to my Z and it is way cool. With the Perf mode shift firmness cranked way up with lt1 edit a push of a switch it will snap your neck between gears, and just another push and it will shift like a Caddy making around town driving nice and smooth. It cost me $6 in parts, I recomend it to everyone.

 

do you mean you did the "performance shift" button? The thing that came on firebirds only. I did that mod as well. It work a billion times better than that stupid b&m shift plus. I wasn't able to adjust it with lt1edit thou. I don't have that software yet.
