      Will this kit work on a 2013 Chevy Tahoe or is there different kits for that

      Does the tuner allow customer to eliminate DOD, change firmness of transmission shifts, eliminate speed limiter, etc.. If not, what does the tuner allow customer to change? Let me know. Thanks

      • The included programmer is generally used to tune for the supercharger.

      So how much work to stock internals and or transmission work would have to be done when buying this product and what other parts would have to be purchased for this to work reliably.

      • This is a complete kit, so nothing else would be needed on top of this for a proper installation. Your stock internals will be just fine as well, however if you continue to modify and add power on top of this I would suggest speaking with a speed shop upon this matter.

      Is it necessary to beef up the transmission? Or can you just run as is?

      • The factory transmission will handle this kit.

      What would be the best cam to run with this supercharger?

      • We actually do not offer any however there are cams specifically designed for supercharged applications. I would suggest speaking with your tuner to ask them what they think is the best option as the answer will likely rely on the tunes written for your application.
