I have blow off valves on my 1991 z32 and it is dying when I give it throttle!!!

What is your question?

When I'm idling at a red light and get ready to take off and push the gas it's like the car almost bogs down and sometimes it does dye!!! I think it's due to me having blow off valves and my maf sensor is reading to much air intake but I'm not sure!! Can someone help

What makes this problem better or worse?

Happens sometimes mostly after I drive it for 20+ miles

How long has your 1991 Nissan 300ZX had this problem?

A few weeks
