The CTS has been a pretty good car so far. I have the UUC lightweight flywheel, wait4meperformance ECU, and Magnaflow exhaust system. I haven't been back to the track but my best pass so far bone stock has been 13.4 @103 MPH. I am hoping to get to the low 13s next time I go out with these mods. I autocross whenever I can too.
