LSJ turbo intake manifold restriction HELPP
Im running those zzp lsj intake manifold adaptor plates for the lsj.
My maf cuts out if i run more than 14 psi of boost, starting around 6krpm.
If i turn the boost down to 12 or so, i can rev the enging all the way out. But at 14/6k i can monitor the MAF Hz drop and the car/rpms freeze.
Does anyone run these plates? or have information that the stock lsj manifold is too restrictive for my to4e 50 trim .63?
I do have a 2.5" exhaust catless as well

when i did the build last year, the manifolds were kind of pricey. So for the sake of getting the car back together, i went with the plates.
Its 2.5" intercooler piping, the maf housing is a little under 3"

Everything was tried..we explored any may issues that could be holding the system up.
Also, 12 psi isn't a stock pressure because it was an LSj sc. Now its an aftermarket turbo that pushes much more air than the m62. So whatever pressure I set it to, its kinda far from stock

I can't remember, I'd have to ask my tuner. But it the frequency would climb normally with the rising airflow and then start to stop around 5800rpm and the car starts to slug. Then at like 6k the freq dropped to like idle freq when still pushing air at 19psi

I mean, it feels like a clogged cat! Car completlry falls on its face. Unless I run 12 psi or lower it seems to rev out well. The waste gate dumps well at that lower psi. Even at 15psi it did but as soon as it hits that high rpm spot, gives out and the waste gate dump sound horrible

Anyone Wanna Take A Look?
I dont know how to view the HP file, i dont have the soft ware. but my tuner posted on this forum. Maybe you guys can view it. the tune has changed since then slightly.
