Hello Travis,
We get to play with this stuff all the time and I can promise you no gain until your at least 125 RWHP over stock then it is actually measurable.
We picked up a couple hundredths of a second at the track in back to back testing at this power level.
At 700 RWHP we picked up 20 RWHP from a Standard LSA to a Ported LS3.
So it is all about Demand vs supply of air, you need to have the demand before you can take advantage of the supply.
Ted.
