One of my friends said that every engine is different. And while I agree, I don't think an OEM motor would be so far different that the engine AFR's would vary enough to need a whole new retune on the dyno.

Thoughts?

Back up the truck....did you pop your motor?

Now to answer your first question. Was it just the motor or was the ECU replaced also? The tune is linked to that specific ECU Vin# so they would require a retune.

I agree with Dreamer and DE, I would recommend getting it back on the dyno just to double check everything.
