Hey guys, I'm wondering what some mods are that would add power to my 5.0 without voiding the warranty, or at least mods that are easy to hide if they do void. I have flowmaster super 10 catback exhaust, AFE Stage 2 dry intake, and I run a 93 octane performance tune from 5 Star Tuning. Yes I know the tuner technically voids the warranty, but it's much easier to hide than some other mods

 

If you're asking about a Coyote 5.0, you might want to post in this forum:

which is more specific to that engine.
