VXAM7N3 > VXAP1N6 ???
 

I recently had my ECM/TCM rolled back. It left with VXAP2N2 and Came back with VXAM7N3. After speaking with my tuner, they are curious as to why it would be rolled back so far. I then asked them what they're preferred strategy to tune would be and the said that they prefer VXAP1N6 for reasons that they discussed with me.

Im curious to all those that have had their rollbacks performed, as well as Bill's thoughts on this. Im not trying to impose anything, just would like to hear some discussion RE: the two strategies. Maybe Bill has some electronic trickery up his sleeve that im not seeing perhaps? (always possible :D)

Thanks,
Jay

This is obviously a Bill question. Have you tried to Call? I know they're hard to get ahold of but it might be quicker.

Im not particularly in a rush on this. As my tuner sent me the VXAP1N6 tunes... and they worked.

So my confusion just got compounded.
