Well, the engine restrictions aren't based on results or applied to specific teams, that's true. But that means a team isn't being penalized because someone with the same engine is winning. They may be at a disadvantage because they can't make their LS6 run as well as someone else's LS6 under the same restrictions, but that's not the fault of the rules. Put that way I don't think it sounds so bad.
OTOH, if no one can make a TRD engine run as well as the LS6 then that may indicate an inequity in the restrictions. If GARRA doesn't want their (comprehensive) engine restrictions to appoint a dominant engine then it's logical for them to adjust those restrictions.
So if it's possible under the engine restrictions to take any of the approved engines and make it as good as anyone else's, then teams only succeed or fail at doing so on their own merits. Is it really something to complain about if a team can't get as much out of their engine as others have? Are they "racing dyno sheets" any more than they would in a series with more open engine regulations?
Unless you mean "racing dyno sheets" as bemoaning the usual state of affairs in motorsports (it does seem to frequently be an accurate description).
