The new Haltech Platinum plug & play system for the 350Z is an excellent upgrade for those with fored induction. This same ECU package allowed us to make over 860 horsepower on our 350Z Greddy twin-turbo. See the complete specs in the link.
The Pro EFI Pro 128 ECU System is a state of the art package, which includes many standard features which are not found on other ECU systems, such as traction control. See the link for specs.
