Yeah, not surprising. Guess that's the difference between a corporate approach and a hobbyist approach. ($$$$)For reference, I was able to do a Q&A with the team that tuned the Coyote engine for Ford. WOT tuning took them a month, part throttle and transients was about 6 months, and cold start/warm up was about a year. To be fair, they had to tune it for perfect starting in all conditions.
