Nah, im saying when I bought the car the owner had the std. bov fitted due to being defected. The car felt really restricted above 5k. I fitted the hks sequential that the owner gave me, reset the comp, the "viola", dont ask me why, it revved so smooth to 6500 -7000 rpm.
Im not saying this is a solution, or starting an argument, I'm saying this is what happened on MY car.
