The Trailblazer, Envoy, and Rainier models have undergone security adjustments to enhance their performance. The timing has been fine-tuned, idle has been optimized, the rev limiter has been modified, and throttle response has been significantly improved. These changes are designed to provide more power and allow the engines to run longer even when operating at elevated temperatures. This setup is specifically tailored for demolition derby applications.
