first off make sure the nipples and the metal pipes crack off ok, if not then 50/50 acetone and atf on them couple of times and leave to soak in for day or two.
if you want to grab a set of these they make the job ten times...
well it's set to that and hasn't gone wrong yet!!
might have a torsen diff to sell soon if you're interested? bought it for one of mine but doing vag box instead.
don't suppose you can scope the crank sensor and see what it's like at 4,000? or chuck another one on if you've got a spare?
the times i've had them play up they've given more of a hard cut rev limiter issue though.
they do seem to work well top end that's for sure. mine picked up well after 5,000 then when we put cams in and billet flywheel it picked up a hell of a lot quicker, just wanted to keep revving. set the limiter at 7,900rpm. temped to stick 197/200 crank, rods and pistons in it, arp bolts on and...
had cranks sensors causing a hard misfire/cut but not like yours. would say look at what the lambda is doing, had a run over the last three or four weeks of iffy sensors either not bringing up a fault code or bringing random ones up. had some head scratching for sure!!
