Teams such Mercedes, Ferrari, Renault supply some of the teams in F1 with Engines that are usually last season's engines, which are typically at least a second slower than the engines they themselves use!!! Or the customer teams tend not to have a full engine mapping to unleash the true power of the engine.
The only teams to use year old power units in this era have been:
Manor 2015: used 2014 PU because they only just scraped enough money to compete in the season, but had to use the 2014 car, which could not fit the 2015 Ferrari Power Unit even if they could afford it.
Scuderia Toro Rosso 2016: used 2015 Ferrari PU in place of Renault because of the fighting between Red Bull and Renault. By the time the PU deal was done it was far too late to get 2016 PUs because of suply lead times.
Sauber 2017: They chose to say with the 2016 Ferrari PU on the grounds that it would save them money, the packaging was well known to them and they didn't expect a large jump in performance between 2016 and 2017.
As regards software, I'm sure the programs are available to the smaller teams. They may not use the extreme mods, such as Mercedes' Q3 mode, as it shortens the life of the engine and they cannot afford to have unreliability and pay for extra engines.
The performance differences between the manufacturer teams and the customer teams is largely due to chassis quality.
