AT what power do they become so restrictive that only a single TB will be more efficient?

Plenums? This thread is about TBs Dan.

And how much for uprated ITBs?

Unless I'm mistaken, I run a single plenum too, I have seen multi plenum designs in the past but only in design.

30-130 would be easier for you, unless you intend on changing your suspension and new wheels/tyres for 1/4 you won't get the traction (at Elvington). Look at Rich at TOTB, good terminal, not so good ET. By your logic Rich should have been running 9s all day long with his power.

You're still just going by opinions so here's another couple of questions to add.

Do you know the control characteristics of butterfly valves?
Have you gone for DBW linear control?

Here's a clue as to why you think your response is better.
