Message Ive had a car Ive been fighting with for awhile now, the car is probably 85% correct as far as building boost\power. Ive been researching, reading, and I cant find a direct answer or solution. The car took forever to build full boost, about 6500rps before itd get to 12psi...found out I had the wastegates hooked up to the factory boost solenoids (they are gt525 turbos), unhooked them, and the car went right into boost, but still laggy. Replaced old Blitz BOVs with stock recirc valves, MUCH peppier, but not quite fixed. I boost it and it takes about 4-5 seconds to get to 7psi, once it hits that, it jumps to around 12 to 14 psi like it should Any ideas???

Mod list

gt525 turbos
new style 615cc nismos with 300 degree fuel rail
brand new long block
old style JWT dualz
Unorthodox pulley set
FMIC
stock manifolds with 2.5" DP's, and HKS hyper exhaust

Ive checked for boost leaks 14 plus times! System is tight!
