I read about the hp/torque gains. Are they worth it for $1300 plus 6-8 hours of labor. I’m running fanabe fatback, Megan racing, takeda cai, RR racing tune, I will be install apexi smart controller which has amazing throttle response. Highly recommend this product for gs350.
I was thinking about purchasing it but I hate the rapsy I hear in multiple YouTube videos. How do I eliminate the raspy. I don’t like raspy cars at all.
is it worth buying?
