Confirmed with HPF that they have decided to make the N54 their next tuning project. They are currently looking to pick up a 335 to start working on asap. This is turning out to be a real banner year for the N54.. Contact HPF if you want to be on their email/mailing list for more info as it becomes available. I can't wait to finally see what the real limits of our engine are. There are gonna be some scary fast 335's out there in the near future.
