NNBS Tahoe wastegate sizing
Hey guys, I'm trying to figure out what would be the best wastegate size for my set up. It's an fully built ( forged pistons and rods) all aluminum 5.3 Bored .20 over accompanied by a MP T76 Q trim with a .96 AR. I'm running a 3" down pipe that enlarges to 4" and its going through a Corsa 4" diesel muffler. I would will be pushing 16-20 lbs daily driven with the option of turning it down to 12lbs at minimum. I have already ordered a JGS 50mm BOV and I inquired about their wastegates and the gentleman pretty much told me that the 50mm would be to much for the 5.3 and I should go with the 40mm so what are you guys running and what do you recommend? Other post I've search are mainly for people on stock bottom ends and only want 10-12 psi max. Thank you
