DJ Tighe posted in this thread earlier today. I can attest to the quality of his work. I did the RCM purchase, send to DJ, replace the tuned up RCM, send him the OEM, and it rests in a bag in the trunk, just in case.
Oh, I had the BAS/ESC light on, the check engine light, and the car would crank, but not start. I tried again and all was well. Checked the tech files here, they are amazing, and I ordered the RCM as soon as I got home. No real problems since.
