Henderson Performance Technologies will be in the process of publicizing on the website several GM (General Motors) Vehicle Performance Packages. These packages will be designed from successful combinations of performance parts we feel best optimizes your vehicles performance, which is based solely on superior performance parts, and the perfect vehicle tune to meet the customers needs. The information will soon be available online for you to research and decide which route to take when improving the performance of your ride. The five packages will be categorized into stages that will include a detailed list of parts for each stage pertaining to a variety of performance vehicles (Chevrolet Corvette C5 / C6 and Pontiac GTO) built by GM from past to present. These stages will be:
Introductory Stage Stage 1 Stage 2 Stage 2.5 Stage 3
The products we will be using for each stage will have a significant increase in power and torque based on your vehicle baseline numbers (horsepower and torque from factory or the horsepower and torque of your vehicle in its current state.) Each stage will be able to allow you to start the upgrade process slowly on your time schedule. Each stage has been designed, based on the large selection of performance parts we use, to be compatible with one another allowing smooth transitions up or down our performance scale.
We look forward making your performance goals come true. Continue to visit the website to check the status of the performance packages, which will be publicized very soon.
Thanks,
Henderson Performance Technologies
