 Trulli won his first Grand Prix in Monaco |
Renault's technical chiefs have tweaked their engines to improve power ahead of the Montreal Grand Prix. "The changes for Canada are performance improvements to the RS24B introduced at Imola," engine boss Rob White told the Renault F1 website.
"These are tuning changes, including new cam profiles, to improve the maximum power of the engine."
The French team are second in the constructors' standings after Jarno Trulli won his maiden race in Monaco.
White believes that Trulli's win has given the team an important confidence boost as the season enters the halfway stage.
"Viry was buzzing after the win in Monaco," said White.
"Monaco is a special place, and an important race to win.
"It was fantastic to see Jarno cross the line first and then to hear La Marseillaise during the victory ceremony.
"The win brings us confidence, but also strengthens our resolve to repeat the experience."
