Retune needed after new OEM motor?

phunk

Going from one stock engine to another will warrant considering special attention to the tune and logging, but I wouldnt be so dramatic as scheduling a tuning appointment before first start up and test driving, etc.

However, since this is following an engine failure... regardless of why I believed the motor failed, I would take into consideration the possibility that the existing tune may have contributed... and for that reason I might consider getting in position for tuning/logging before pushing the new engine hard under boost.
