You can adjust the gear ratio and tire size with a tuner so your speedo reads accurately. Another option is to have Ford or someone with the right diagnostic tool do it for you. That way it won't affect warranty. That's what I did when I went to 33's before I got a tuner.

Not sure that's possible with 2008+......if anyone has done it successfully with a newer van please post your experience.

Oops, I didn't realize that. Mine's an 06.

Wait, I might need it now, see my thread "That dreaded metal on metal sound" It all depends on what Randys ring and pinion says tomorrow.
