I don't know about 4.6L's but I know my 3.8 didn't need a chip and I'd assume the v8 wouldn't either. It's a pure bolt on. Although you'll have to dye grind the upper manifold throttle body inlet so they're both the same size and there's no ridge. You won't get as much of a gain out of it as you would if you got ported intakes and heads. Then you'd be getting full potential of the throttle body. Going too big can hurt hp too.

The back story:
It has been quite a while since I have posted, mostly due to the fact that my motor exploded roughly 6 years ago. Since then the car has...
I'm giving changing my motor mounts another try, and instead of going through the torture that removing the mount+bracket out of a 2x2 inch space was, I was wondering about the service manual's procedure for changing them.
The one thing I wasn't sure about was that it instructs you...
