Default SD and emissions

So i went in for emissions today in md and they said too many not readys to pass. The car is a 2000 ws6 ta with an s475 turbo and 80 lb. injectors. It only has 41k miles and I've had it since it was new. I used to have a procharger on it and it passed fine. It's running on hp tuner's 3 bar os, in open loop. I've read that you can't turn off the maf codes or it won't run but i tried it anyways and it runs fine. I've only driven maybe 50 miles or so since the last re flash so maybe that's the problem? All of the readiness tests say complete on hp tuners except the o2 sensor. There's no dtc's either. I'm still kinda new to this tuning stuff but the car's coming along nicely. Do i just need to drive it more or am i missing something?

" All of the readiness tests say complete on hp tuners except the o2 sensor."
"It's running on hp tuner's 3 bar os, in open loop."
This combo causing the issue??

Then you missed tuning out some codes related to the o2s. Go back in the list and turn off everything that has the word "Bank" in it.

I definitely missed some. P1133 thru P1156 are the ones it took to get all tests complete. I was just under the assumption that I was allowed up to two incompletes before it failed which is why I was confused. I'm still not sure if it'll pass or not but there's no dtc's and all tests are complete. Thanks for your help
