My boost gauge is steady up to 10 lb than bounces around 10-15 lb then is steady till 20 and bounces a lot up to 25. Is this normal? turbo issue? or just plumbing?(i have t in map line)
Boost gauge bouncing is fairly common because you tapped into the map sensor line. The map sensor releases a little bit of air, hence the bouncing. Try to move your boost gauge closer the the intake on the map line. That may help.
