I've been messing with the turbo error correct to try and fix it but I still dont understand it.
If anyone could tell me how it works, I'd be on my way to figuring out how to have complete boost control using the stock boost solenoid for pump gas boost and race gas boost.

What side of the error correction table should be 0'ed out, the left or right side.

Well, I got complete boost control using the stock boost solenoid almost worked out.
Just have to test stability, test race gas boost, make some logs and write a how-to.
Hopefully, Ill have it all worked out by the end of this week.

I spent some time on this but didnt have the time to work out the same issues you were having. (big family)

However thats not really what this thread is about. You can be more accurate by doing some mechanical changes and then curving the maps for what you want.
Sometimes finesse is better than brute force, consider that helpful advise.
