ok, i have a s1 rb25 and i tried swapping to the z32 maf. when in the garage everything was fine, when i got her out on the road everything went to ****. at about 4800-5000 rpms the car cuts out like tries to shut down. I dunno what's wrong?

here's my specs for reference - s1 rb25, pfc, walbro 255, rb20 actuator on rb25 turbo, fmic, tial bov vented to atmosphere, koyo alum. rad., and stock everything else.

This is a dumb question, but did you change your MAF setting from the stock RB25 MAF to the Z32?

Just wondering if by chance you moved it closer to the turbo.
