Sam Tordoff said this in 2013, at a time when there was a different boost figure between cars running the Swindon Engine:
'Boost levels are determined from a rolling average of the two previous rounds and apply to models rather than to a single team'.

For the 2015 season, when they reviewed the boost adjustment process - a base was set for each car/engine type. This assessed the car and engine in combination, not as independent units.

The resultant regulation from 2015 was worded as:

'1.11.2.a. The throttle body size and/or restrictor and/or the maximum permitted rpm and/or maximum permitted turbo boost of individual cars may be subject to review and validation after round 9 of the Championship and/or subsequently at any further time during the Championship by the
Administrator, who may implement a variation by way of a Bulletin issued by the Co-ordinator giving a minimum of 24 hours notice'

Which they then did during that season, and boost adjustments were again made on a car-by-car basis, regardless of engine type fitted.

I also wouldn't take the fact that a regulation has not been used in the past, as a reason why it won't be used in the future. Until 2017, they had never used a rule that applied a CoG adjustment (AFAIK) - but the performance of one car model made them consider that as an option.

the old adjustment process you refer to was done on a lap time calculation. they ditched that. it’s now done purely on an engine performance basis and disregards the lap times. the regulations now state there will be no race by race boost calculation.
