Some carburetion mods were attempted (to reduce fuel consumption). Unfortunately, the "tweaks" were dialed back while in transit to the west coast (a field mechanic - unaware of the nature of the mission - simply saw that the carbs were out of spec and "fixed" them).
The engines weren't "hopped up" in any way, but the aircraft were lightened considerably.
