I've ordered from AM many many times and had never taken more than two days for the item to arrive to my house, they are prob the fastest shipping company I have ever purchased from!
I got the 87 street, 91 performance and 93 race for my '11 GT. I have the tuner sitting next to me, but I need a pee cee to download the tunes to the programmer. I'm gonna hit up one of the nerds at work to help me with the transfer...as I have a Mac. I'm also using the stock air box...for now.
Since we are expecting 18" of snow in Detroilet tomorrow, I don't think I'll be uploading tunes to my car until the summer tires go on...sometime in March-ish.
My CAI & Tuner ordered from AM, tracking says delivery to be 3 days from now. I also have ordered from them before (tire/wheel package) and they are dead on with shipping. I'm like you, I can't wait.
