Yes, but the target is a Cap (maximum) not a nominal value. If you add enough air to hit that Max Torque Limit, it will likely reduce spark advance, then you need to tune. The goal for those staying stock is to run as close as possible to stock tune max torque limit, for those we recommend our modified LGX TB, the kit discussed in this thread is very likely to need tuning.

Remember, the manifold snout has the area of a full circle, the TB has the area of a full circle minus the projected shaft and blade area. Such that:
72 mm Stock TB effective WOT area = 3350 mm^2 (not a true full circle)
72 mm Stock Manifold area = 4070 mm^2 (true 72 mm circle area)
76 mm Ported Manifold area = 4540 mm^2 (true 76 mm circle area)
84 mm Soler TB effective WOT area = 4550 mm^2 (not a true full circle)
So with the stock manifold, you gain 720 mm^2.
With a ported manifold you gain 1200 mm^2.
There will be nothing worse than a step down (discontinuity) from 80mm TB to 72mm manifold, the straight taper in the Adapter Plate definitely eases the transition, especially when compared to other Adapter plates that are not tapered. We are 100% sure that adding a radius in such a small distance will cause flow separation.

It depends, the devil is in the details. Here's is where the difference between effective area and the true area explained above comes into play.

Agree, this is the best. TB only adds capacity, use it like this to its full extent.

Thank you, and yes, apply it properly for best results.
Notice we do not claim any power increase, we simply claim our TB's will give much more air at low throttle for a better response. At WOT we can only claim larger air handling capacity, the power will come from applying it correctly as you said.
Thanks,
