No, My car is not stock and yes I have EM (UTEC)

Im just at a middle point where i have both, but i need to run two different boost levels (one for meth and one for pump). The ext. wg. I have has a 1bar spring, so at 25+psi you see bleed off, but the ebcs allows you use the top port on the wastegate and put downward pressure on it. Im just curious what most people would use.

Im also trying to figure out which one would be safer for a failsafe on the meth, i think the ebcs is easier.
