"I've yet to see 500+RWHP with the STOCK unported Eaton and NO JUICE!" My mods with the addition of a 2 lb lower and another superchips tune made 510 HP at the tire on JDM's Dynojet... What would that be on the superflow? Prolly 480 at the tire...that's the difference. If I decide to add the 2 LB lower and heat exchanger I'll be sure to test it, document it and post unbiased data. I'm pretty biased about dynos, but... truth be told... I don't BS on information.
