Well, couldn't stand it any more. The old LS1Edit software was stolen with the old truck and I've finally decided to replace it with HPT. It's back to play time again. I guess I've actually got two vehicles to tune at the house with the addition of the 07 Classic. I will be able to pull timing out of the tune for some 300 HP NOS runs now. And no, not 300 HP shots on the 07 4.8L engine.
