Hey guys i had a thread early askin about why i couldnt put out any boost...well i fixed that problem it was a boost leak...well now i have another problem...for some reason i cant boost any more than 6psi even when i turn my manual boost control almost all the way up...even when i turn it all the way down it boosts 6psi??? any suggestions on whats going on??

I will try to help. Is wastergate stuck open? Can put less than 10psi on hose to it and see if moves? No higher will blow diapharm. I assume turbo is free. Not running tight.
