WTB 411 ECM

Hello,

All of mine are already programmed for my vehicle but you can do whatever you desire with that tune. Save it or immediately overwrite it, your choice. It is also not tuner locked in any way.

I'll send you a PM.

I'm looking for another 411 ECM that has not been calibrated.

I'm still looking for a 411 ECM.

I am curious why you need or want an 0411 and do not just use a newer DBC P59 Blue/Green. The 03-07ish Express van P59s or any of the DBC P59s can run anything. I have noticed the P59s run better than the 0411s do. GM made improvements to the P59s that is noticeable even in a stock vehicle.

That's what the customer wants.
