Debating 5.7 or 6.1 swap
FAST has a couple systems you could look at. They have the ez efi and efi 2.0. The 2.0 is a plug and play comes with throttle body and is a direct plug and play has self tuning but can do anything from traction control, boost control, nitrous controller, 2 step and the list goes on. The ez efi is self tuning system, boost and nitrous friendly and works with bolt on parts cam swaps. Both good systems that can be purchased in different configurations. Check out fast man efi he has great prices and will set you up with the system that will best suit you.
