Messing around with various simple air bleeds at various points in the pressure lines, I was able to push the boost up (as has as 21 psi, but I yanked that bleed off immediately) and hold a higher boost level longer, etc..
But I've noticed the "flutter" that others have talked about (and I have a bone stock intake, so the factory airbox/silencers do not "hide" this sound). It seems to happen when letting off from partial throttle at around 2500+ rpms.. Seems logical that it would be the surge valve, but why would it be acting differently? . I'm thinking the faster spool (from my experiments, and others CAI systems)is bringing higher pressures earlier in the rpm band, and maybe this is messing with the stock SVA some how?
