> Same mods as me, but I have a LS6 long block which is much better flowing heads then the shitty 853 heads in that dyno. My cam is a little bigger then that one as well. Thunder racing got nearly identical numbers as my setup…Dont see how my numbers cant be believable when its being done.

Given ThunderRacing has some parts on the car, maybe that might clue you in how they were able to make those #s? Hell, I know some tuners who spray some nitrous accidently in FMICs while on the dyno.
