Im in the process of tuning my car with a SAFC2. All my supporting mods are in profile. I dont have my fuel pump or a FMIC installed. I want to know what a good boost level on the evo16g to tune for before running out of fuel.

I was going to start at about 12psi and bump it up to about 14psi max if possible. Do you think I could get more than 14psi tuned out of the stock fuel pump?
 
Also ive been trying to tune out my knock at WOT at only 9psi. Im running 550's and a 2g maf and from my understanding that it makes the motor run lean. With the settings at 0 I was getting up to 35 counts of knock buy 6500rpm.

To get my lo trims around 100% I needed to add about 8-13% in low rpms and 16% in the high, and ive noticed that most people with this set up needed to do that.
I then ran the 16% accross the high fuel adjustments and it helped a lot with the knock down to about 20 counts.

To get the counts down to about 4-12 counts I ended up with about +22-24% in the upper RPM's. When you add the fuel should you bring it accross the board or can you add lets say 22% at 5200 and only 20% at 6000rpm. Shouldnt it need more fuel the higher the rpms. It seems to help if I tune it this way. To me this feels a little high for only 9psi of boost. If I start upping the boost im going to have to add a lot more right. How did people tune this setup with the safc1 with only +30/-30% adjustments? Does this sound about right.
