Default boost stuck at 15 - 08-20-2020, 10:21 AM

Hello all,
I just installed some brand new index 12 injectors (due to leaky injector) and coded them with protool.
First start I heard a lot of new noises. I think wastegate rattle only at start up, and some squealing and tinging rattle noises that would come and go in rhythm. I could only hear the noise from the cabin but not under the hood, so I let the car warm up

First drive. When I put my foot on the pedal the car jerks/stalls/looses power constantly. I pulled over and drove again and it went away, before coming back a few minutes later.

Logging: I logged this morning and found as soon as I start driving the boost is stuck at 15 and stays there the AFRs are at 20 the trims jump between 0 and 90.

full bolt on 2010 n54 recently I changed the spark plugs and coil packs but I had no issues after changing them. I broke the clip to the pcv vent hose but it looks to be plugged in still.

the car is undriveable any help would be appreciated,
Thanks

PS my caution light is stuck on and solid during driving and even when the car off and locked

Which tmap sensor is on the car now?

Do you have the n20 option checked in MHD & option 1 for n20?

I installed the new n20 MAP sensor and the car is now drive-able with no codes. I turned on the 3.5 option in JB4 as well. However, my trims are reading from 0 to 200. I did a 2k to 5k 3rd gear pull in JB4 MAP 2 since I'm in the middle of the city and didnt want to push it too hard.

Log is attached

I feel a little dumb, but seems like everything is good now. My y values in JB4 was 30 and when the trims past 30 they disappear from the HUD. I was reading the time lol the 200 was 200 seconds. Now that everything works I will find some where and do a pull to get my logs read.

Thanks for the help.
