How do you hit peak boost at 5500 rpm and hold peak without building more boost to 7500? Is it becuase the recirc valve opens at 8 psi? Ive never seen a centrifugal setup hit peak boost before redline, usually they keep building pressure. If theres something I dont know (probably the case), is there a way to make a larger higher flowing compressor hit peak (8psi) boost even sooner and hold it to redline? Either way, thats pretty bad ***. Are the kits workable with the LTH yet? PSI/Power drops?

it has a lot to do the VVEl and the VE of the VQ37VHR engine, same blower on a VQ35HR is doing 14 psi and over 470RWHP .
