Default Single Turbo 2jzgte vvti where is you MAF sensor mounted???? Help please

I hate to do this but I have exhausted my resources..

I just did a gte vvti swap and everything works except I am having a stalling issue, when you come to a complete stop and tap on the gas , the rpm goes up and when it drops it just fall on it face and stalls out.

O2 sensor I wired properly.
TPS is working properly
Maf is working properly.

I am thinking it's the location of the maf sensor, it's right after the TB right in front of the P/S pump.

Where is the best placement for the maf sensor on Single turbo setup? The car has 6266 Pte and stock injectors, Stock ecu no piggyback in a 99GS300.

Thanks

The factory location is before the turbo. I would move it there and see what that does for you.

You need a recirculating blow off valve.

It's definitely your blow off valve not being recirculated.
