  • 2005 CTS-V (Z06 Corvette 5.7liter) Performance Tune

    Friday, 15th of August 2008 at 6:53 PM

    Tomorrow we're running a performance tune as well as putting on more performance parts on a 5.7liter Cadillac CTS-V (405 horsepower and 400 ft-lbs of torque stock);



  • Texas Speed 233/239 .620 .610 112 LSA camshaft

  • 15lb flywheel

  • Stage 3 Clutch

  • Katech Short Shifter

  • TPIS Longtube Headers

  • Magnaflow mufflers

  • X pipe

  • dual 2.5 inch piping

  • K&N intake

  • Stainless brake lines

  • Vented, slotted and drilled rotors

  • EBC yellow brake pads


    • Currently the car has been running on a Diablosport Predator tune which is not nearly sufficient for the camshaft/15lb lightened flywheel we will be installing. The stock dual mass flywheel on the CTS-V's weighs in at 42lbs, nearly twice that of a standard Corvette!
