These graphs were from my old 83 G20 with a GM 1-ton L05 crate engine. First dyno was mostly stock with headers, 2nd dyno had 1.6 roller rockers, Z/28 valve sprongs, intake manifold, and 454 TBI.
Thank you for confirming I am not just crazy. My tuner was very happy with the results. I told him I was less than impressed.
