just wanted to make a few things clear, is it true that the greddy turbo(b18c1 kit) can't boost more then 12lbs witout it acting up cause of the internal wastegate? thanks

 

must be a rumor then, no one knows

 

i have the greddy ki-- no not a problem-- the turbo will flow up to 20 psi nicely-- it tapers right at 18 from a friends expeirience and cant hold it well but a good boost controller helps -- like the AVCR from apexi and HKS EVC

 

this is kind of a hard question to answer because some people have problems holding 10psi and others hold all the way to 18psi. so it depends on a lot of things. sorry if this is not the answer you have been looking for, but yes some people have held the power while others have problems.
