I made this tune based on the 20-20 with a little different fueling, would anyone mind checking it to make sure i haven't messed anything up to bad. For my 2002 Lb7
It's a compressed file. If you right click the tune, you should see "send to" in the pop up window. If you move your mouse to that selection, it should have a pop out menu that says "compressed (zipped) folder". Once you have the file zipped, you can post it as an attachment.
