I have an HKS supercharger and at idle the mixture is between 14-15:1 idles fine drives fine but it seems slow when I floor it it feels like it had more power when I bought it and after 5500 rpm it's gutless I have to shift because it won't get higher yen that it doesn't sputter or anything just doesn't do it and it runs rich at that rpm anyone know how I can adjust this? Feels like I'm nt getting boost even running at a good mixture at a low rpm

 

What is your ems?
