$25k is not a bad price considering it includes the install, Pectel and tuning. Two questions I have as I looked on your product list for the Gen 4.
1. Does the Pectel interface with all the other sensors on the car, like seat belt and seat sensors, air bags, antilock brakes, etc? I saw you had "Note: Pectel EMS are not ODB2 compatible" on your website describing the Gen 4 kit.
What does that mean exactly? What parameters are not going to work, if any?
2. Can you post any videos showing if the throttle response is improved with your tuning over the Vipers stock crappy throttle response? God I'd wish somebody could come up with a reasonable cost fix for NA Gen 4's.
Cheers,
George
