What Did You Do To Your HHR Today?
Installed a new atmospheric release Forge valve today, I think my car is happy it came with a brand new yellow spring, I notice a couple pounds of boost have returned, that seemed to have slipped away in 1.5 years running that spring.
It also goes PIISSSSTTTTTTT. but not as dramatic as I had hoped..
