        50mm? wow thats huge. You might actually see a big drop in low-end, but the top end will be redonkulous..

        We have found that 46mm throttles on a flat six with a displacement of 3.8L seems to work pretty well, and they still have some room in them to up the displacement more (but the engine bores wont take anymore room)

        I did 46s on a carbed 3.4L...way too big...dropped them down to 42s and the car ran a whole lot better and around town driving was good.

        Where did you get these ITBs anyways?
