Always a wealth of knowledge. Someday I will shake your hand for providing so much useful info.It adds that much mis-calibration . I uses a 2g maf with my last setup and swapped to a drawthrough maft. The a/f curve remained pretty much the same falling to 10.5:1 by 6K and staying there to redline. I switched it to blow through and it ran me to 9:1 or richer. My airflow number went up . But fortunately I have dsmlink and recalibrated. I used the BEP bolton housing with the t31 turbine wheel with that same 6031 compressor (60-1 ecover) and I couldn't get over 52 lb/min at 32psi. I basically had an scm6031 with the bep housing which doesn't appear to be smaller than the .63 bolton PTE housing and has a better volute design.
