Has anyone had success with a speed density tune on a 2016 Z06 LT4? E92 pcm.

I have a 2015 Z06 A8 (Z07 Package) that I am setting up a base SD tune as I type this and going to do a little logging here shortly. I'll post some updates on how it goes. This is the first one I'm doing with EFI Live. Although for years I solely used EFI Live my hands were a little tied since the C7s were released. The new DI motors and new ECMs are a new animal. Can be very challenging and rewarding at the same time.

you do it SD open loop or close loop ?
I had a shot at this, the ve table dialled in nicely on cruise and idle, however there was no boost at all once full throttle was applied. The pcm obviously went into a limp/fault mode, I just couldn't find the table to combat it. I will have another attempt shortly.
Try B302/B303. I noticed them after I finished up a 16 Z06 M7 this week. I ran into the same issue. If they work please report back. The other approach is to dial in MAF then create a histogram of MAF/MAP reported airflow error and apply to the VVE MAP table.
Are you getting a MAF DTC immediately on engine start...?
