Good dyno numbers?

[CD07GT500]

Just got the 2011 GT500 3.73 on the dyno with the 100 octane tune Justin gave me when I ordered the 800hp kit. Put in a full can of torco with half a tank of 93. Spark advance on the datalog showed 21 degrees of timing and 44% fuel pump duty cycle. Wide band readings were ranging from .78-.80 lambda. Do these numbers look ok? I was hoping for 700+ since I have longtubes/off road h pipe/1 piece driveshaft as well. Got 675 HP 642 torque at 6300 rpm on a dynojet. 75 F 300 ft altitude 60% humidity. Mods in sig!

Nothing wrong with those numbers. Mine just made 674/631 sae after l/t install with a almost identical mod list. That is with very similar conditions and *19 0n 93.

Cool initials on the blower. Hey Justin, next time I see you, will you sign my blower? Lol

I have close to the same mods minus elbow and throttle body ( mine are still stock ) with a 2.5 pulley and stock drive shaft. On 91oct and 17 degree timing I am at 629/623 to the wheels

Humidity at 60% could be part of the issue. My car dynoed 15hp lower than previous reading. Original run was done at 15% humidity and the latest was at 51%. The car also had 3 more degrees timing and a full point leaner.
