Is this a vacuum leak cause I can't find it :(
What I did last night was adjust the boost bypass a little lower because it wasn't closing perfectly. I also sprayed a little throttle body cleaner in the tb to clean it and I took out the MAF and cleaned it.
I also cleaned the K&N drop in filter.
I noticed that when I started the car, the stock boost gauge showed -70 vac or all the way at the lowest setting.
I assumed it was a vacuum leak.
I then listened for it and I head a leak where the EGR tube connects to the motor.
I pulled out that tube today and found that it was cracked around the flange.
I siliconed it with high heat silicone but my boost gauge reads the same thing.
The boost gauge goes a little higher than -70 when the car is in drive and the car doesn't shift any harder than it used to but I sprayed TB cleaner around all the vacuum lines to find the leak but I really can't find it.
I guess my question is.. do I really have a vacuum leak?
