seems right on track for 17.5-18 psi. could he not push any more psi? was that why he was crushing the bpv?

as far as identical to vf39, it is, except the wastegate is sprung a bit stiffer, thats why people say it holds better to redline.

you can do the same thing with a vf39 with a wastegate helper spring, or even a vf30, 34, 43, etc. (mebbe the 43 is sprung heavier too) top end flow is exactly in line between my vf30 and my vf39, same flow. verified via logs.
