Shake down runs on Patrick’s CTS-V

Last night we got the opportunity to start shake down runs on the next World's Most Powerful CTS-V! Having just wrapped up the largest build in the shop to date, we wanted to do some "soft" runs on the wastegate springs to make sure all was well. The setup didn't disappoint at all! With James Karger (www.lstuner.com) making the tuning adjustments the car made an astounding 1038 bhp (903 rwhp) on just a measly 10.5 psi of boost! Check out the video to hear the newest monster we've created!
