Google it.
Anyway, LL, I have seen 16gs creep. But dear GOD… I think you forgot to put a line on the waste gate. 3rd gear pull. 30PSI!
WTF!
Most of your fuel trims are fairly inline. All the problems from earlier in the day are solved. You need to get the MAP wired in so it actually reads. 
Then we get your GM dialed in and I can tune the top & WOT stuff.
Well… whenever you decide to port the turbo a little so we can keep the boost under 23-24psi. 125% IDC @ 5500 rpm on 550’s!
Holy shit!
I’d like to see some real airflow numbers when we get it dialed. I think that will help with the choppy-ness you’re getting too. Either way its driveable now. Get the MAP working, and I think the rest will be easy to iron out.
If not, I got an extra 2g MAF or two we could throw on and see if it solves it.
Gettin’ pretty tired of your GM. :reloading
