    2012 shelby, with some ugly dyno numbers

    did not get a chance to log it during the dyno runs since it was more of an impromptu kind've thing. But I did get a chance to mess around with an aeroforce gauge on just a few WOT blips, was looking real rich, like high 10s. Obviously nothing official or scientific.

    Mods:

    2.59 Pulley, JLT 127MM CAI, CJ 65 TB, AFCO Dual Pass w/Fans, it's also tuned. NGK TR6's.

    Stock these cars put down numbers similar to this: (Note AF on the dyno sheet was taken from a tail pipe sniffer)

    wow, those do seem low. My 08 with upper, cai, axleback, and tune was at 550rwhp. Why do you think it's off?

    Ya, as said above. Heat exchanger pump is not working. Once that is fixed I'll have to log the calibration see if there are any other issues.
