Installed RAPTOR 150 Pump -- Lower boost!
Switched out my walbro pump for a raptor 150 pump. I also installed the twin line kit for dual injection pumps.
With the walbro pump I would get 64lbs of boost.
With the Raptor pump and twin line kit I get maybe 54lbs of boost.
I increased lift pump pressure to about 30psi. Still no change.
Why the change in turbo boost? If anything I expected more.
