I just got back from my local speed shop and I did a dyno run today. I say my most power around 4300-4500 @ around 309ftlbs for the best torque and 234.5 rwhp. The only mod I have now are MSD coil ,flowmaster cat-back and an airfoil @ the throttle body.

My ATI-P1SC arrives this Friday and I'll install that with a MSD-6AL. What should my fuel pressure be at ?? I was running REAL rich (like 10.1 AFR) after 3000 rpms on the dyno today. What do you guys run for a fuel pressure?

1 last thing, I'm planning on running the blower with the 9lb pulley it came with. Any suggestions or experiences?

Thanks,

AC

 

The blower kit should come with an FMU. It's job is to increase fuel pressur in relation to boost. Usually at a ratio of about 4-6 PSI/pound of positive boost. As such, your base fuel pressure should not have to be changed very much if at all (assuming it's right to begin with). You will have to make sure that your fuel pump is up to the added flow and pressure that will be demanded of it.
