Looking at the rules for Turbo Boost (BRB, pg 76) it says you may not move through difficult terrain. The rules for jetbikes (pg 53) however state that they can move "over all other models and all terrain freely". I could argue that the movement rules clearly exempt jetbikes from the difficult terrain issue but the turbo boost rule specifically refers to both bikes and jetbikes so it would seem those rules must take precedent. If I was being pedantic I could also argue that the movement rules say I go over terrain so I'm not actually going through it but that seems a little cheesy.
So, which is it? Can I turbo boost over difficult terrain or not?
