Mbc with an external wastegate

[suprapower1221]

I have a 4psi spring in my hks wastegate. If i would buy a mbc off of drjonez could i go over the 4psi or do i need a new spring. Thanks Steven

Yes you can go over, 4lbs would be your lowest boost level.

I don't know what drjonez sells but if you have an external gate you can use a small regulator and feed pressure to the top of the WG. Much better way than using the bleeder type.

Clifton: I think Doc's MBC's are Ball and spring units to improve spool time.
