engine build for reliability

There are many on the market that are self learning so no need for thousands of dyno hours.

That said I’d probably pass on the $2500 or so needed for a full system at the start. That’s something that can be added down the road

Self learning is a marketing ploy. All OEM systems are “self learning” but only for steady state operation. All the transients, cold starts, hot starts, accelerations are not self learning and are what the dyno hours are for.
