Stage 1 is referring to the actual turbo size and setup. It doesnt necessarily include any further upgrades to the Engine, DCT etc unless certain horsepower levels are desired. Heffner Performance could get into detail with you about that. As for DCT upgrades we would recommend our Spec S clutch setup on any vehicle exceeding the 850hp range for a complete reliable solution. The Spec R clutch takes it to the next level with replacement billet components for even more power to the ground. Our clutch setups are completely built in house for added peace of mind and ease of installation. We have multiple core units pre-assembled on the shelves that can be shipped out the same day as the order is placed. You can visit the SSP Performance website for more info and pricing.
