what kind of boost controller are you using, manual? You know i have the same problem where boost drops to about 11-12 psi at redline.. i have had it up to 16 psi, but it runs out of steam fast. I thought it was my EBC settings, but maybe that is the limit of the BNRs?
If you are using my timing map, i bet you can get at least another 10hp just by tweaking it.. it is really conservative, i think that is why my numbers were kind of low. I did 308 whp at 13 psi, stockport S4 block
