Magnus manifold problems

[NeoStreamGSX]

After installing the magnus smim, my car runs like shyt... took out emission things and charcoal canister, vacuum lines run to fpr, boost gauge, bov, and brakes. at idle my vacuum reads only around 8... and car juss has no power whatsoever...when stock manifold was on, car ran good...i connected a vacuum line to the map sensor, zip tied to something behind motor...car wants to stall out when load it put on. and when more throttle is put on, car barely accel... very frustrating

I would start off by doing a pressure test to see if you have any leaks.

You should see 18" of vacuum at idle. You've got a big leak.
