I was looking at getting the LT4 fuel system put on but wasn't sure if it was necessary

Fuel system mods are a must, especially if you want to run any ethanol, which is almost universally recommended. To summarize from other threads. LT4 fueling is expensive right now (or just flat unattainable) so consider port injection as a cheaper, but more complex to tune, alternative.
