Kimi Raikkonen says Ferrari have taken a step forward by bringing a turbocharger upgrade to the Canadian GP - but is not expecting miracles.

The Scuderia have fallen behind both Mercedes and Red Bull in the championship and struggled to keep pace with their rivals in Monaco.

However, the high-speed Circuit Gilles Villeneuve represents a better opportunity for the SF16-H and both cars have been fitted with a revised power unit. The turbo update takes Ferrari's development token spend to 28, leaving just four remaining for the rest of the year.

Turbo boost for McLaren

"This is a step forward," Raikkonen said. "How much? Time will tell. We would never put a new part in the car if we didn't think it was going to improve.

"I don't expect miracles but it's the right direction. It's like any other new parts we bring, it's not something magic."

McLaren have also brought a turbo update to Montreal while Williams are expecting more points with their upgrades, but neither are arguably as desperate for results as Ferrari.

Having been billed as title challengers at the start of the season the Italian outfit are without a victory in 2016, but Raikkonen was eager to stress that the team are making progress.

He added: "We are definitely stronger in the car and other areas than we were last year. Maybe the results don't show it, but it's not been an easy start for us as a team.

"We know as long as we keep working, it will pay off. The package is improved, but you always look for better results and wins."
