The motor is a 3TGTEU so there is no carby, it's efi.
Fuel is pumped in using a lift and inline pump, surgetank combination plenty of fuel.
timing is fine as it's running on the factory computer with no drama's. I might point the finger at the knock controller next...
And no I will not block the exhaust more and see what happens. Just got a gut feeling it would not tell me anything I don't already know.
