One of the most efficient ways to upgrade the performance of your Nissan 350Z is to have the factory computer reprogrammed for optimal performance. Through enhancing the factory ECU, new found power and torque can be extracted. Through enhancing the ignition timing map, adjusting the fuel map, eliminating the speed limiter, and raising the REV-limiter to ~7100rpm our customers enjoy more power, economy, and reliability. Expect to gain between 8hp and 15hp depending on the vehicle. Customers local to AAM Competition can have their vehicles reprogrammed in our service facility.
