Good Day Everyone,

My 75 diesel boost is not stable. Sometimes I have a lot of power and sometimes I lack of boost. I already changed: O-rings, PCV filter, all other filter, new oil. I already removed the MAF sensor plug, but there was no change.
What I noticed so far: When I start the car in the morning the engine is running well, and have a lot of boost. When It's start to warm up I lost most of the boost. When the engine is on temperature I have all the boost over 2.2-3k, but there is only a little below 2k(around 1.8k), but here is the catch. When I stop so the car is in idle and I press the pedal I have boost again from low rev to high rev. even the wheels spin out. Also my UBP is kinda loud compared to my friend MG ZT diesel. If It's the ITP what type is in my car? It's the 5D330678

Thanks,
Devcore
