Brown truck brought me a gift today. Got my PCM back today from being programmed for the LS.
I used LT1swap.com, Brendan over there works fast. I sent the PCM in and got it back in 7 days. That includes round trip shipping. I sent it out ground on my end. Very happy with his service.
I'm going to do the harness myself using his videos and documentation. I'm ready to get this engine fired up!
