Ford says don't modify your 2011-2012 Mustang 5.0 or your warranty is void

From what I have been reading it is safer to add FI to the new 5.0 then it is to have just a tune. It was said that most of the tuners just applied the tuning of the 4.6 to the 5.0 as in more timing = more power and this was the cause of most failures.
I would say it is more in the tune then anything as there are some with no issue that are beating on the car.

I don't know where it came from that high compression motors are usually maxed out as that is not true.

I agree though that the warranty for me ended when I drove off the lot, same with my Jeep. Let something break and I will make it better.

Gotcha...I missed the "this" in there.

I still think it is BS as there is always more power hidden in a factory engine. Just think there have been a bunch of failures due to bad tuning and Ford has said enough is enough.

There is a video of the testing the Ford Racing supercharger goes through, so they think it is pretty safe to add a SC.

I think it was bad early tuning, too. These motors are no where close to being "maxed out" from the factory.

Knock yourself out guys.

Bad early tuning is correct.
There's not a lot left N/A stock without mods.
The Whipple Supercharger is a safe mod for this engine.
