Appears that way as evident by your #s. Did your atmospheric have a 4" or 5" exhaust connection and what were your torq #s on that pull ? Thanks for the info .

Torque numbers weren't reading well off the dyno so I'm not sure; when I made 790hp it was around 1300 ftlbs.

My atmospheric has a 5" v-band flange that is reduced at the flange down to 4". 4" downpipe, 4" exhaust all the way back.
