Default LS1 Running Rich?

I have an 01 LS from a Camaro swapped into my BMW. Recently the gas mileage has slipped, and the PCM fuel trims are as follows:

Bank 1 short: +3.9%
Bank 1 long: +25%
Bank 2 short: +19.5%
Bank 2 long: +25%

These numbers were taken at idle with an IAT of 107. Numbers while accelerating and cruising were similar.

I have a fairly significant exhaust leak, could that be confusing the computer or should I look elsewhere for the problem?

TIA,
Robert

Any leak upstream or nearby down stream of the 02s will cause problems
