I highly doubt you need to change to a different year or PCM. Most stuff I have messed with will go up to 285 kPa. That's enough to lift the heads in most cases on a stock 4 bolt head setup. What operating system is your PCM?

This makes sense. Your tuner uses EFI Live. There are no Custom OSs for 06-07. That is why he is trying to get you to move to a 04 OS. Now HPT on the other hand has custom OSes for those years.

Better question is why does he need a 3bar? That's a

of boost.
