30%? Sounds too good to be true without some reprogramming, current ECM don't use variable potentiometers, they are fixed. Just sound fishy. The last 4.7 I had power and fuel mileage were not a problem, it was the life of the motor, just not that great. Anything over 130K and things start happening.

So my truck is at risk of messing up if i do it ?

No, it's more at risk if you do.
