My sr's stock bov's recirculated pipe (underneath stock intake) was disconnected, meaning it was basically kinda like an open atmospheric BOV. It did cause my car to run idle/run rich, but from butt dyno, somehow it feels much faster and there's less lag. When I shift, there was no hesitation either. This suprised me, could it be that I'm running lean right now and there's not enough fuel, but when it's open atmospheric, there's extra fuel so it makes my car faster? Here's my setup:
redtop sr, upgraded t28/t3 turbo, with .86 turbine housing, HKS actuator, full 3" exhaust, walboro fuel pump, running stock injectors, HKS actuator set around 11-12 psi. It's probably making around 250-260 flywheel. Am I maxing out my injectors? Your thoughts?
