well i got my forge mbc a while ago but havent put it in till now and i was hearing from eveyone at my meets that if you run the spring that come in the mbc from the factory your boost will taper more. so they said put the other spring in that comes with the mbc, so i did.and they also told me to keep compressing the spring with your fingers for a while before you put it in so it wasnt so stiff, so i did that as well. now i have the mbc turned all the way down and i am hitting 24+psi. any advice would be great. thanks guys.

what is the problem again? the stiff spring isn't for taper, it is for high boost. if you want less than 24 psi, put the soft spring back in. also, how are you determining 24 psi (what gear and what RPM are you going WOT)?

 

I have gotten rid of some taper using the stiff spring on the soft. Read this post I made.
