2g engine bog

[Drewthebear]

I have a manual boost controller on lowest and a greddy type s bov, but my engine bogs and shakes? any ideas on what it is? i was thinking of removing the manual boost controller, i need it fixed asap as it is a daily driver.

Have you done a boost leak test lately?

You probably have a boost leak.

Remove the MBC and make sure the waste gate has its own boost source. After doing so if nothing changes make sure nothing is teed off the bov line and check for lose hoses etc. do a boost leak test at 5+ psi then you are currently running fix the issues and enjoy. Still have plugs after that check plug gap and wires. Check coils and resistor box for in spec ohms and go from there. Remember go from free to cheap to costly when trouble shooting
