how much boost?

[mcm7.3]

So where would be the most common place to have a boost leak? I was thinking the boots could be loose, would this be a good place to start?

That's one place to look.

The o-ring on the compressor outlet, the hot-side boots, the intercooler end tank seals (if you have a plastic-tank intercooler), the cold-side boots, the boots at the intake plenums, etc.

Drive pressure leaks are really common where the turbine inlet pipes merge into the collector. It's a design flaw....nothing wrong with the truck. If you see soot where the pipes merge into the collector at the back side of the turbine housing, then plan on buying new pipes and donut seals.

Could your waste gate be releasing pressure at 20 psi though too? Just something elso to consider.
