Sure, but my 2.5" system is not spooling too bad, especially with a 2560 (compared to a 2554) and a cast manifold. And, it is quiet, not much louder than stock really, and very non-rice.
Makes me want to unbolt the DP flange at the cat and log the spool to see if it makes much difference.

Sorry I'm late to post to this thread. I would like to see my line if that's ok with the powers that be. These numbers are from the last MT.net northeast dyno day in April. 4th gear pull I think. WG solenoid duty cycle is around 50% until it gets close to 14 (TPS based boost target) then it slows down...made 13.3 max. I could probably get better spool by clamping the WG DC to 100% until a few psi before target like you guys do with your megasquirt or like a ball/spring MBC.
