My suggestion would be to find someone in your area that can dyno tune the new engine combo. The injectors probably need to be tuned as well.

Okay, a 30 lb (number that begins with 280-15x-xxx would be preferred) at an installed 43 is about right. Put a scanner on it and if it's running rich it will show a blm of 108 (128 is perfect). Contact Ed Wright and tell him your flowrate is not correct. You need to tell him you have a problem, and the steps you took to determine the cause.
