2004 LS6 CTS-V on the Dyno at New Era Performance in Rochester, NY. The car made 359/356 to the wheels. The only mods are a crappy Volant intake, Kooks 1-3/4 long tubes (With cats) and a 3" dual B&B exhaust. Not bad for bolt ons. Mike's tuning was good for 12 HP throughout the RPM range...it baselined 347 before his tune.
