One of two things is happening. Either the motor makes no power and adding boost results in no power or the boost reference is wrong and its not really seeing 15psi at the intake valve. Or timing. Whether the computer is pulling timing for some reason or the timing was set wrong to begin with and the reference is off. I hate to say it but this is where these mix and match fuel injections can be a total nightmare and not worth the headache.
