I have the BP kit installed on my car currently.

If I got a new motor from Nissan, would I need to retune it again or is it just a simple swap of the motor, fire it up again, and give it hell?

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?
