Hey guys been a bit. I don't get to drive the Ralliart much anymore always in the company car but free gas is hard to beat... Anyway went for a cruise the other day and noticed I was boosting like 1-2lbs less. Cars just been sitting tune hasn't changed no leaks. Would I be right to suspect weaking wastegate spring?

 

Boost leak possibly.

 

you're using the 16g with internal wastegate right?

check for free movement of the waste gate and actuator arm, and yes check for leaks.

 

External waste gate

 

is it spiking to normal level and tapering off really bad? or just hitting a level that is lower than before?

 

Just hitting 5and change when I was originally hitting 7and change. I'll grab my logs and show you.
