Stage 2 Computer Chip

The Jet Performance Stage 2 Computer Chip (MPN: 29429S) is engineered to unlock the full performance potential of your 1981-1995 GM vehicle by overriding restrictive factory settings. This module actively optimizes critical engine parameters, including air/fuel ratio, ignition timing, and transmission control, to maximize horsepower and torque output. Specifically designed for vehicles with existing modifications such as performance air intakes, headers, or exhaust systems, this Stage 2 chip is a step up from the Stage 1 version, which is intended for stock engines. The chip also has specific requirements for optimal performance: it necessitates the use of 91 octane fuel, a 180-degree thermostat, and a free-flow exhaust system. Additionally, this chip is exclusively compatible with vehicles equipped with a 4.10 or 4.56 rear axle gear ratio. Installation is described as a simple, plug-in process. This product is 50-state smog legal and comes with a Lifetime Warranty from Jet Performance, with Automotive Stuff acting as an authorized dealer.
