Cool, thank you. I'm picking my car up on Thursday with the new turbo and exhaust and I'm guessing that due to the stock injectors and intake my closed loops will look pretty good.
To tune boost I was thinking of running on wastegate pressure to see how the AFRs look and log and then.... look at the MAF load and AFR and adjust accordingly. I can do the arithmetic to determine how much I need to adjust MAF load for the given voltage by looking at the AFR error percentage.
