The 8th digit from the left on your VIN identifies the engine. #1 = LB7, #2 = LLY.

O.K. I have a #2 in the eighth digit this means LLY. What does that mean?

it means you have the next generation motor.... you have lots of reading to do in the LLY section. Use the search to find all the differences, pros, cons, etc.

oh and welcome aboard!
