But ill feed the noob

Remove mbc

Install independent good vacuum line to bottom port of wastegate

Install know lbs wastegate spring.

Drive car

If it over boost either...manifold design/wastegate placement suxs, wastegate is too small, or wastegate is a peice of shit

If boost hits target psi, and holds steadly thru rps...install mbc per directions

If boost now doesnt hit correct target or over achieves....buy a new boost controller



Anything eles?

That will be all. Thanks. Just got Tapatalk last night, First post to Zilvia as well. And yes it’s old but I knew someone like you would answer.
