The customer service is excellent. I had the K & N CAI and tuning installed on 07 Z06. The initial rwhp 446.1 and rwtq 410.2 and after the installation and tuning 480 rwhp and 446.2 rwtq in the Texas heat at 2:00pm. I am very happy with the increased power.

Top Notch all the way! They've transformed my 2007 Z06 into a screaming beast with 545 RWHP!
