Street Runner Computer Chip; California Edition (1990 Corvette C4 w/ Manual Transmission)

Hypertech Street Runner Power Chips replace your stock PROM, which holds the settings for fuel flow and spark advance. This is a Stage 1 chip that improves the spark and fuel curves for better performance. It provides max power at wide-open throttle but does not affect the idle or part-throttle settings. This means your mileage and emissions aren't affected! The Street Runner Power Chip is designed for use on a stock vehicle using premium pump gas (91 Octane or better). Wake up your ride with a Hypertech Street Runner Power Chip!
