Can you turn up the waste gate? .3 bar is only 4.4 psi. The problem is they used a L-48 motor. Which does not use good internal components. So they probably kept boost down to make it last.

With such a low RPM peak. I would check out the air fuel ratio. You might also look at the timing. With turbo motors you want less total timing than a N/A equivolent.

Without changing the turbo size or system. I would ensure that the exhaust outlet and muffler was as free flowing as possible. L-48 heads are very restrictive and the cam is for very low performance.

Is your turbo a custom setup ? Been toying with the idea of a turbo or a low profile supercharger for my 383. Dont want to cutt my hood though
