If any of you guys want to try it, i have 2 Hypertech modules in stock.
I had this on my G37 for a year before i went boosted. I can honestly say its worth every penny.
Also, there is no charge to go back to your stock MAP.
) You can easily install and remove changes with the module including decreasing your red line (valet mode), even limiting your top speed for safety
Pm me for pricing
