yesterday i went to the track and i nottice that my car losses power from 5500rpms to the red line
i ran 4 times and all the times were the same, the car feels so strong until the tach reachs the 5500rpms, when that the car stops pusshing
ç
the bost remains on 10psi and the air fuel gauge shows a rich mixture.
i wonder if could be a timing issue? its the only thing that comes to my head, because there´s no boost leak, the 10psi stays there until the red line, or maybe i´m maxing out my maf?
