– Alfa Gulietta

”Came with 116HP. Drove home with 153, and also about 30% more Nm from the bottom.“

– Toyota Previa

”Hello. New fuel record 400km drive without even trying. Down from 0,54 to 0,5 per 10km. Much more comfortable driving with less shifting and better low end torque. Not to mention it's awesome to feel that extra kick when stepping on it! Thanks for job well done!“

– Berlingo HDI
