Default Can you flash a tune on an ecu that already has a flashed tune?

The next mod I'm looking at is the NW Mani's, which will incidentally require a tune due to the part leaning out the engine. I'll want to go to the custom InMotion tune however I already have the LET tune on it. Will that cause any problems trying to flash the InMotion tune on it? TIA
