"Received my programmer a few weeks ago and installed on my G37S as soon as I got home. Very easy to use, just follow the directions. On-screen prompts pretty much make it idiot-proof. I did notice there seemed to be a slight power increase and torque increase. Wasn't huge but helped.
Will probably soon be installing a Stillen Gen 3 Intake to make additional gains." —Guy B from Atlanta, GA bought a Hypertech Max Energy Sport Programmer for a 2009 Infiniti G37, 3.7L V6.
