Transfer your "Midnight Club: Los Angeles" saved game from your Xbox 360 to a flash drive.
Plug your flash drive into a PC and open USB Xtaf Explorer. Click the "Extract" button and navigate to the saved game on the flash drive. Double-click it to open it.
Right-click the extracted save game and select "Open with Hex Workshop" to open your saved game in Hex Workshop. Click "Tools" and "Base Converter." Type in how much rep you had on your saved game in the "Decimal" box. Copy the number that appears in the "Hex" box.
Click the binoculars logo in Hex Workshop and paste in the number that was previously in the "Hex" box. Click "OK."
Open the "Base Converter" again and type in how much rep you want in the "Decimal" box. Copy the number that appears in the "Hex" box.
Click the highlighted number on the Hex Workshop main window and paste the number you just copied into it. Click the "Save" tab at the top of the screen.
Drag the edited saved game back into the flash drive. Reattach the flash to your Xbox 360 and the next time you start a game your rep will be the number you changed it to.
