That's what the customer wants.

I'm still looking for a 411 ECM.

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

I'll send you a PM.

I want one that I can program myself. They have been scooped up from the junkyards around here. I have two others from a 2003 and 2005 6.0 Yukons.

I'll buy one and pay the shipping.

Stock, 5.3, 4l60e, ect.

Not around here. I can find the 2003 up ECM everywhere, I have two of them.

Looking for a stock calibrated 411 ECM, shipped to Catawba, NC 28609.
