In engine module, measuring blocks.
log the following groups:
114: N75 duty cycle
115: boost (actual / expected)

Find a quiet stretch of road.
Start from a slow roll, start logging.
change to 3rd gear, accelerate to full throttle (wide open throttle).

Do a few runs then put the data into excel to make a graph and view the data.

231 is the low fuel pressure...230 is the rail/high pressure.

Going to look at your boost data today...then later...I cannot open the data?

I have the same issue. It's fine most of the time but last week it wouldn't boost over 5 psi then 2 mins later it was back up to 11 psi then 2 days later it wouldn't go over 7 psi then same again 11 psi. I'm running a gfb DV+ so doubt that's my problem so wouldn't mind knowing what you find  :popcornsoda:
