Blow Off Valve Is Causing Car To Stall!

get a lean spike instead of a rich spike as the MAF double-counts the airflow.

You mean a rich spike, as the air has been metered multiple times due to the turbulent air, you end up injecting more fuel causing a momentary dip in torque and quite possibly a stall event.

TL;DR, install a Haltech Elite or S3 or R3, convert to DBW, throw all ancient shit into the bin and enjoy the car.

If you block off the BOV entirely you will get reversion out of the MAF and get a lean spike instead of a rich spike as the MAF double-counts the airflow.

Hmm that sounds pretty bad lol. So that applies for all cars right even the s15's that have the bov blocked off?

I don't need a rich spike. I'm still blowing black smoke after my tune when flooring it lol. I wonder if a jammed actuator has anything to do with it
