BMW-Sauber is set to make more steps forward, after the boost provided by a major aerodynamic upgrade for the recent Spanish grand prix.

The German squad is still not a player in 2009, but boss Mario Theissen insists Barcelona proved a "comeback" after the dire situation of the opening four races.

A double diffuser was not part of the Spain package, but the formerly controversial concept will be fitted to the F1.09 for the forthcoming Turkish grand prix.

"To be honest, I am looking forward to Istanbul," said Nick Heidfeld, who on his 32nd birthday moved up from 13th on the grid to score two points in Spain.

"This (in Turkey) is when we get another new package with the double-decker diffuser. Hopefully we'll take another large step forward then," added the German.

It is also in Istanbul that BMW plans to reintroduce KERS, after taking the technology off its cars for Barcelona and next weekend's Monaco grand prix.

It is understood that, compared with the previous 2009 system, the team's KERS will be running in a modified form from Turkey onwards.
