My inlet is already opened up to a 102... but no need to drill and tap anything.

I also am only running a ported LS2 TB as Pat mentioned.

Where I was going is if you do have a pressure drop behind the TB, your only option is to go to a bigger TB.

How much boost are you loosing?

Yea I followed you. I am going from 205KPA in first gear at 4400 RPM to 196 at 6000. I can only assume it will get worse with more revs.

I'll be there!! I don't expect much tonight though... I am definitely out-flowing my intake and I have a suspicion its the elbow on the TB. Boost starts falling off early and yesterday I hit 188KPA by about 6150 RPM. I wouldn't be surprised if this thing is done making more HP at 5250... a shame considering I built and planned it to rev to 6500. Now I'm not saying HP is falling off by 5250, but I can say with confidence that its not making any more power beyond that.

If you got the room you could make a 4" pvc race intake like me to use at the track, its better than running no intake and sucking the hot radiator air in

I need to use my intake tube... thats where my meth is tapped into.

And its silicon. Entirely possible that it collapses a little.
