Jet Chip Powertech Performance Module, 4.0L engine, stage 2, -03
Computer controlled engines on cars and trucks are run by programmed chips that tell the engine what to do. Factory chips compromise between fuel economy and performance. The Jet Powertech Performance Chip overides the stock computer chip and maximizes various performance characteristics. New programming adjusts spark timing & the air/fuel ratio to tune the engine for maximum power when you need it. Provides improved performance under demanding conditions such as towing & wide open throttle acceleration.
