MitsuStyle - View Single Post - Ways to lower my spool-up rpm?

Speedfreak · 03-23-2012

Tuning the wastegate? When I was sold the wrong springs for my wastegates without knowing(way to heavy), I noted that spool was sooner and quicker(on Shanes dyno) than previous runs. Meaning if you put pressure(boost) to the top of the wg I'm guessing you could possibly keep it fully closed until you need to regulate the pressure and thus create the same effect? For reference, when I got the correct springs, it spooled slower and later.

Just a theory, but I believe its done already by some?
