Your question is not clear? I think what you are ask is about turbo spool
The exhaust A/R determines spool. I run a .63 A/R and spool around 3,200 rpm. With a .43 A/R you should spool earlier so maybe around 2,600rpm with full boost at 3,000rpm. The spool happens quick and boost hits very hard
The .70 on the compressor wheel determines the maximum boost you can run. I run a .70 A.R which is for big boost. You are running the same compressor A/R so you should be able to boost 25psi or higher
