It's not about valve clearances it's about valve spring rate and you could quite easily have some tired/lazy valve springs there that won't hold the boost. I have seen this in all types/makes of engine and while the 1J might not be particularly prone to this prob that doesn't mean yours isn't suffering it. Very hard to diagnose though but the engine will sound flat and on the road it will rev but won't pull....kinda feels the same as when you cam timing is out. It's the only thing i can think of as the boost difference means there has to be a flow increase regardless of where the turbo is in it's eff range. More air has to equal more hp if all is sweet with the engine, fuel and timing...ergo something is amiss with the engine. got a pic of the turbo just to confirm 100% it's a TA45?
