NASCAR solution to Toyotas Dominance

Toyota has dominated the Nationwide Series this season, winning 15 of 22 races. Of those victories, 6 were from Kyle Busch. So there's a new rule that restricts the Toyota engines, to level the playing field.
In Cup there is no such rule, dispite the 9 victories in 20 races, but of those 9 victories, 8 are from Kyle Busch, so the reason for the cartoon... It's not Toyota, it's Joe Gibbs Racing and Kyle.
