RE: Header comment on the 6.1L engine
And also, if you get a MTX, get a short throw shifter. I got one for the stang, and shifts much better I think.
And for the tuner, at least for one I can get for stang, it will hold 3 tunes, so you can have one for 87 octane for daily driving, then when you want to get agressive, they can make a tune for 91/93 depending where you are at. The super here is 91 octane.
