My car is lightly modified with a e9 turbo, mr bov, samco copy intake pipe, and 3" turbo back exhaust with oem injectors.

The car sometimes stalls rolling up to intersections, reversing then going forward and always stalls driving up my driveway on an incline into my garage. When I press clutch and press the brakes the rpm drops and car stalls.

I've included a log from a stall going into my garage - I'm looking for confirmation that I have a stuffed stepper motor or something else

Thanks.
