Horsepower?
I am trying to find out what the HP is on my 2012 GT Premium 5.0. I read somewhere that in the Spring of 2012 it went from 412 to 420. What gives?

Thanks Griffin. Now, is it true that the Roush exhaust system increases HP?

Ehhh, wont really do anything power wise, it will give a nicer sound.. Power will be unlocked through a tune, intake, headers.. Things of that nature..

roush exhaust weighs like 20 lbs less than stock, also it looks like its alot more free flowing

Okay. Another noobie question. Someone said my GT will need high-octane fuel. True or false?

NA just regular octane, SC needs 91 or greater.

This is false.. Run premium, you can run regular but it will adjust to make less power.. The 5.0s need premium to max the most power..
