 Complete the following phrase:  The team was involved in a second, more serious dispute at the German Grand Prix when FIA Technical Delegate Jo Bauer referred the team to the race stewards over what he felt was an illegal throttle map. The 2011 season saw teams produce more downforce by programming their engines to force more air through the exhaust and over the diffuser. This practice was banned for 2012, with the regulations dictating the position of the exhaust outlet and requiring teams to observe a linear relationship between the degree to which the throttle was opened and the amount of torque being produced by the car. Red Bull were accused of abusing this relationship in medium-speed corners, allowing their throttle to be more open than it should be for the amount of torque being produced. This would allow more air to flow through the engine and out the exhaust, which was angled to direct exhaust gasses towards the diffuser. Although the effect was less than that created in 2011, Bauer felt that this practice had the potential to produce more downforce, and even serve as a rudimentary form of traction control if applied under certain conditions. The race stewards cleared Red Bull of any wrongdoing, stating that the team had not broken any of the rules, and the team was permitted to start the race. However, the FIA passed further regulation changes ahead of the
