Mike or Sam - Is there a way to tune the car so that when the car is in 6th or 7th the boost will be less? That might save a few transmissions that aren't built.

Know I am not Mike or Sam, but the Z's factory ECU doesn't control boost, that's controlled either by WG spring pressure, manual boost controller, or electronic boost controller. There are some high-end EBCs that can do gear / speed specific boost control, but I am not sure if any of those work on the Z or not.

You are right.

My HKS EVC can do that.

The HKS EVC 6 electronic boost controller can be programmed for per gear boost. That said, you can't run boost any lower than wastegate spring pressure. Most of our kits ship with 6psi springs, so that would be as low as you could go.

Also, I don't know if you knew this or not, but your right foot also functions as a manual boost controller that can change boost pressure on the fly.

I was born with a tragic birth defect on my right foot: PB distum pedis. also known as... Lead Foot.
