What's the exact parameter/scalar/function to adjust for transient fuel? I see at least a half dozen items in the tune that look like they could be it....

Transient fuel multiplier & Transient Constant Multiplier. Id try setting them .031 (all xMul cells of the latter)

Then set the accel and decel transient parameters to zero and move up from there
