No idea. I imagine they are cheap ones. Is that a factor?

Sorry to reopen a old post...but did you ever sort this problem out..as mines still doing in.plugged in a boost gauge tonight i am out 11psi, on what is ment to be a 280 mapped ecu...now floor it and its ok..give mid power and she splutters some times..when she splutters floor it and its ok..could it be plugs..i fitted new ngk ones about 3 months ago and leads.
thanks
I cant be 100% no, i will video the cut out as its not boost cut as such as its as if its fuel cut etc...i need to change a few vac lines so manybe that will help
it sounds reminiscent of the sort of cut i was getting with an ecu that was supposed to be chipped and after fitting an ecu from hml no cut running up to 17-19 psi of boost with stock plumming...could be the ecu!!

96' 850 T-5 estate
94' 850 T-5
Ignition Leads?? this was what was causing my similar problem.

I am kinda thinking of sending me old T5 ecu for a postal remap then i know for sure its been done then...i am running 12 psi at the moment, but need to put my boost gauge somewere and try and find somewere to put the pipe through the bulk head
Yeah didnt know if i should crank the MBC up and see if she will run at 14 or something...see if my problem is still there or gets worse
I had the same problem it xas crap leads and plugs
I'm guessing you have an s70/v70 as you don't have a boost gauge.
If its a fueling issue then i very much doubt that turning the mbc up would help it, apart from seeing if it will boost higher and show up the problem more.
How "jerky" is it? Is it a splutter or more progressive?
I say this as mine has got a boost problem, but its very progressive, just like you can feel the boost coming on and off. If its like mine then i doubt it would be plugs, leads etc and more like a bcs or actuator problem

No its a 850 i have...i have a boost gauge yes. Didnt do it at all this morning on the way to work and i havnt touched the MBC or anything.
I have replaced the plugs, leads, cap, rotor, etc about a month ago.
I have a 16T to go on this week or next now with a actuator so maybe see if its any better then..as for strength..its mild..its like someone cutting the fuel for a split second...its not harsh at all.
Like said when it does it..if i floor it at the same time it goes away..its as if its only there when your loading up and holding the boost rather then if you floor it and make it work its fine.
Example..over taking a car the other morning...long open road, just put the power down half way..but full boost and she pulls out..starts to go..splutter, goes, splutter, goes splutter, pulls in and i floored it, fine..slowed down, go again, splutter go splutter slamed it down fine all the way to the red line...
maybe something i am going to have to live to deal with since fitting the MBC.
Or maybe try a different MBC maybe
Call me crazy...half of me wants to crank the MBC up that much that it does boost cut out then i know what that feels like, and i will know its not that now - but dont want to bend a rod .lol
Thanks chaps
