I saw something on the auction site... a plate that you can use to bolt a ls2 tb to a ls6 intake...it looks like a reducer....idk it this would help or hurt performance?

That COMPLETELY defeats the purpose of going to a larger TB.

As you go from a LARGE pipe to a medium size to a small size pipe or air intake, the velocity or speed of the air increases and flows into the cylinders quicker.

so you are saying that going to a 90mm tb to a 78mm opening would increase the flow into the cylinders quicker?

Not so sure this is true when you have a negative pressure on the small end and atmospheric (14.7) on the large pipe.
If it were true why would NASCAR run restrictor plates to slow down the cars?
What it should do is increase throttle response and decrease top end power, giving the illusion of a faster car.

It is something worth looking at or into.

Illusion? I would think most ppl would trade increased throttle response and decrees top end power any day.
