why get a 80mm TB when stock is 78. Call Bob at Peak speed in Colorado. Here is the aurthor of
the new 90mm and now 102mmTB. He takes your 07+ Manifold and welds on to the nose a LS2Tb
from a corvette or now they have a 102mm Tb that has been completed. It's a great mod. Adds
about 15-23 HP in the entire band. I love mine...
