Hey guys. My colbalt boost gauge is still on backorder so i picked up a $40 sunpro. Same gauge as i have in my idi. The needle is real jumpy. It will flutter 2 to 3 psi whenever there is boost. Any idea. It tops out around 18. Is this normal with stock sticks?

thanks guys

 

i used a sunpro until i got a autometer. it flutters around at low boost, but anything over10-15 it steadys out. someone posted that stock is about 18 max

 

ok thanks.
