i just noticed my boost pressure gauge is showing the boost climb and descend slower than before. i have just replaced the line on top of the hose on top of intake manifold. the tiny one by where it says turbo. i believe it is a black hose with a red line. i usually have a reading of 20 in the inhg area. now it reads about 18. could something else be going on here?
