Shelby GT500 Bolt-Ons - Stage Might

PHP's Stage 3 performance upgrade delivers stealthy muscle for Shelby GT500 MustangsHorse Sense: The Stage 3 name suggests there might be other stages as well. Stage 1 ($775) consists of the PHP tune on the SCT flash tool, along with the cold-air kit. PHP's Stage 2 kit ($975) adds a 2.6-inch blower pulley (and compensating idler) and a 160-degree thermostat to the Stage 1's inclusions.
