Injector Duty Cycle increase?

Injector Duty Cycle increase?
So my buddy and I installed my Banzai Diff Brace (great product btw! Cleaned up my driveline and my shifts big time!) along with my Eibachs and Tokicos last night. Prior to doing this when I would run the car WOT (when there wasn't wheel hop) my injector duty cycles would remain around the 74-76% range. After installing the diff brace and suspension change and going out and "testing" the setup I look over at my commander and see my maximum Inj Duty Cycle is @ 85%. Typicall hard pulls are putting me up to 78% where as before it would be 70-72%.
I wouldn't think these changes would do anything to injector duty cycle %'s unless the Banzai Brace really cleaned up that much slop in the drive train. Thoughts?
The car has the standard mods really:
M2 CAI
M2 Medium IC
Greddy Elbow
Stock Twins
PFC (S Kan Tuned last year)
Full Exhaust (including 3' downpipe, Hi flow cat, RB muffler)
550 Primaries
1200 Secondaries
Cosmo fuel pump
Aluminum AST
and now Eibachs/tokicos & the Banzai Diff brace.

probably temperature differences. your ecu should be compensating for intake temps, and I am guessing you have been checking your duty cycles during the day when it is warmer... and now you checked it at night, when it is cooler.
cooler air, = denser charge = more oxygen = more fuel = higher duty cycles
