As the title says, does anybody have any experience of Garrett 2860-5/HKS2530 in 2.8 stoker?

Graph is now 1 year old, but showed a "lazy" 500 rwhp at 18psi compared with a "peaky" 574 rwhp with the old set-up (GT-RS terbs, Apexi 136mm I/C, Greddy plenum). These days power is closer to 550 rwhp, so haven't really gone backwards at all in power with the new set-up (actually up 20hp off boost at 2000 rpm and up 130 hp at 4,000 rpm). Rev limit set to 8,500, but power curve doesn't fall over even after 9,000.
