Toyota Racing Development has had the kind of success most manufacturers would boast about in the NASCAR garage.
Five wins and eight poles in the first 13 races should have TRD riding high.
A few high-profile engine failures has drivers frustrated and TRD looking for answers in time for Sunday's race at Pocono Raceway.
David Wilson was named this week as the acting president and general manager of TRD. He called drivers, crew chiefs and competition directors from Joe Gibbs Racing and Michael Waltrip Racing together on Friday to discuss the changes ahead and the plans to boost the engine's durability.
