There's air velocity, reversion, flux capacitators and a million other things.
And it's not BS, it's on TPiS's web site. 90/90 vs LS6 gained up top but lost a little down low on a cammed car with stock LS6 heads. On a stock cam and LS1 heads, it'd be even worse. If memory serves, I've read other magazines with the same results.
GO forth and let the GMMG FLOW like it was supposed to.
