Same i-level or other i-level does not mather. Simple story: When you retrofit nbt in a car that came with factory cic and you startup ista/p or ista+ for programming it Will tell you to replace the nbt because it does not belong in the car. With ista/p there is expert mode So you can just "ignore" the replacement and update all the other modules without any trouble. If you read the ehole threat you should understand this Better!

Cheers!
