soo i have another mate that has the exact same problem but has started since he fitted a 12 pound TS actuator....... it even has the rough idle afterwards (apparently....)
it has been tuned previously for 10psi so its gotta be overboost and by the look of a log i took with forscan it seems to cut fuel as the STFT goes from 24% to -4% as soon as it happens
Who tuned that file ?

he bought it like it, he has dyno sheets from some place in brissy cant remember what its called though.... whys that JET?
I would love to data log, maybe when hp tuners sort out there ba stuff. The car I was playing with hit like rev limiter then run rough, when I upped the desired boost the problem went away. If you google the problem lots of people have it. Just looks like the people that have resolved it are staying tight lipped.
yeah i just done the same thing, but just changed the overboost threshold and the problem went away on the BA, but then i changed the WGDC to 1 across the rpm range and then it decided to boost to 20psi sooo i quickly changed that back.....but ive done that on another ba and it still only boosted to the desired boost? the one that spiked has a 12psi wastegate though so i wonder if thats why?
From what I understand, correct me if I'm wrong any one. You will need to set your desired boost to what boost you actually want, then play with wgdc until your actual boost is the same as your desired boost.
