Well, I thought they all came locked. But I dont think much..lol! I have no way of tunning it. Thats why I was just going to get a 05 ECM send it to him..or whoever and get it tunned. I have everything order for the basic 3.4 swap. Just the whole tunning my car so it dont mess up!!! I think the only person who has a tunner that is somewhat close is Dan and he is like 3hrs away! My buddy has a EFI Live tunner but I don't think they will tune the Grand Prix only the V8 ones.
