I have a manual 2014 ZL1 and had some mods installed yesterday. When I took the car in the pre-install dyno showed 509 RWHP / 497 RWTQ at 10.3 Psi AFR 11.3 The pre install run had a Roto fab CAI, VMAX 87mm TB and a catch can.

So, I had installed the ATI 10% pulley, ARH shorty headers (ceramic coated), Roto fab big gulp and tuning with HP tuners. End result was 550 RWHP / 540 RWTQ at 12.7 Psi AFR 11.9.

The temp during the runs was 68 F and 64% humidity at an elevation 765 feet MSL in Murrieta, CA on 91 octane, 98% injector duty cycle.

My question to the members of the forum is, do these number seem low for the mods completed?
