As far as the tune goes, I think he did just mean that it is just a solid idling engine. A lot of the time engine idle better after we resize them becasue there is less blowby down low at the port windows. Which some engines even when new dont have the greatest fit down low.
Im sure all these guys know how to tune. BUt generally yes, an engine should slowly "load up" after idling for a bit of time. If it does just sit there and idle for a very long period of time and not load up at all then it would indicate the LSN is on the lean side of the window.
Thanks guys for the feedback!
