Ok finally fixed some more boost leaks after dropping the motor in my new shell. I had a buddy through on a wbo2 and tune the car to about 10.9 afr. This was at only 9psi. I turned boost up to about 13psi and started logging.
Car will not knock untill about 5800-6000rpm when the IDC's hit about 96% and then causes 4-6 counts of knock till redline.
Now if I pull fuel and get the idc's lower I still get knock, if I add fuel the idc's go to high and I get knock.
Now what would cause the 550's to max out at only 13psi on a 16g?? My buddy says that 550's are way to small for my setup but many of people have made more power on 550's and a 16g.
