These Hypertech Street Runner Power Chips are replacements for your GM computer's stock PROM, or memory chip, which holds the factory settings that control your fuel flow and spark advance. These Hypertech chips replace the factory settings with performance-oriented ones. Hypertech Street Runners are designed for stock cars. They provide maximum power at wide-open throttle and delay converter lockup for smoother shifting, but don't affect the idle or part-throttle settings, so your mileage and emissions aren't affected. So, if you need more performance, then these Hypertech chips are just what you should get.

Installed this chip on a 1994 Chevy Silverado with a TBI 350 to solve my problems with wide open throttle lacking power. Installed this chip, which goes in line with the original chip, and at wide open throttle it has made an extreme difference. It's like a different truck. Hasn't effected other setting like advertised, but it has made the truck sound more aggressive at idle and part throttle. Great product, would recommend it to anyone. ...read more
