/\ That's an interesting idea . I would have thought making the port bigger would have the reverse effect 
These two logs are in 2nd (blue) and 3rd (red) on the same settings.
Second gear is more consistent and showing hitting 200ish and holding it . Pretty ideal for street 'situations'
Except when nailing second on a corner - thank goodness for DSC is all I can say !

After much dicking around trying to get rid of the hesitation I was getting when the SSV opened I concluded that it was due to the Blue injectors in Sec. position as I never had the issue with stock injectors there.
Not wanting to swap out the injectors , I rewired the setup so I could control the rpm it opened and experimented at various rpm.
Every rpm I tried was still an issue so I have eventually settled on 1500rpm because it does idle slightly better with it closed and that is low enough such that it doesn't cause any issues (except at warm up).
Car drives perfectly well and I see no drawbacks at all . *Power is slightly down below 3000 but Turbo spoolup is the same .
Another big advantage is that I no longer have wild AFR swings in the 3500 - 4500 range .

Car drives perfectly well and I see no drawbacks at all . Power is pretty much identical either way . Turbo spoolup is the same .

The funny thing is that it's my butt dyno that really can tell what is going on . The car is now just at that point where with just me in it I get that real shove from 5000 on up that is very satisfying . But with someone else in the car it loses that feeling .

well the only answer to that problem is.....Ding ding ing. You guessed it. MOAR BEWST. Go ahead and tap out the maf. you know you want to. I remember you saying your motor could handle it. Maybe the introduction of W/M to help out a bit
