Just seeing if it’s worth it to flex fuel kit swap on it and do I have to upgrade the injectors or the ones for 2018 GT 350 good enough to run it. I’m only looking to get around 600 hp of it with everything else I’ve done.

I run the Proflex gizmo and love it to say the least so in the event you run e85 and get a tune for it that would absolutely be felt by the ol' butt dyno

It seems like the only upgrade that wakes these cars up, short of forced induction. 40-50+ whp, right?
I've decided to keep mine stock, but I'd be interested in hearing the experience of those who've done it.
The only other bolt-ons I've seen that are worthwhile is an intake manifold (requires other mods for fitment), throttle body and headers. I don't like the headers mod because it changes the sound, and I haven't heard an exhaust setup that's better than stock (something I've NEVER said before).

If you track the car and E85 is abundant in your area, then yes, it is 100% worth it. On top of adding a few ponies to your car, it does help with CHTs while revving to 7k+.

Your gas mileage will suffer. And that is being polite. I get about 12mpg mixed city/hwy with my Mach 1. YMMV (pun intended) with the 5.2.

Definitely not going to get 50hp
