Im not 100% sure but I think it 2.11....Does that sound right ?

I have a Predator U7198 for a 99-03 corvette. I used it once and restored the factory tune. It says the tool is unlocked so does it still need to be sent back to be unlocked or is it ready for another vehicle and, if so, I have my original receipt and all so does it cost to get it unlocked ? thanks
