Yea it starts runs and drives, this is weird. Is it because I loaded a DSP5 tune on it with the wrong operating system? But with the stock tune file that Bdsankey gave me with the right operating system in it should work right? Unless someone already put a new/used ECM in it and it's not the same vin? Maybe? Confused ? lol

I will say that I forgot to mention, when it took the first time and it was successful. It started then died, then I started it again and it fired up, and now it fires up every time

It'll be hard for us to diagnose remotely. I would try doing a bench flash or sending it to someone who's experienced with flashing these modules.
