If you could open the Ecu and tell me what the chip says, I will tell you if it is still the correct one and what spec it is,
It should have a -31 not a -34, it should peak at 25psi dropping to 21psi,
The Chip will work or it wont it wont be in between,
I would look for a fault somewhere, As a guess it sounds like a fueling problem the way you describe it,
1st to check is fuel flow I would run the return line in to a can and time it over 30sec this will tell you if it is flowing correctly with no boost pressure on it,
Then check for fuel line kninks,
After that get someone with test equ to test it.
