This test has been done 100 times before. And it's pretty much always the same. With the fast being worth little to nothing over an ls3. The after numbers are right in line what most would expect. So again my point is most shouldn't expect to gain 20rwhp off a fast. Because if this thing was makingg 470 480 like lots of other cam only cars, do you really think a ported fast would put you at 490 500?

The original poster gave a before and after dyno, and recalibrate his tune for the new intake....
Was the before setup a ported stocker or a stock one?
would love to see the graph of before and after.
and is this with a 90 or 102 mm throttle body?
