Hi, Ive got the HRC kit and I still cant get the fuel pressure quite right. Its fine when im not under boost, but if I floor it it begins to studder and my a/f guage drops to lean. If I gradually get into boost it does not studder but its not reaching full boost, the 8psi for the stage two kit. Also the brass adjustment knob on the fuel regulator is turned almost all the way in, for the highest fuel pressure. So why is it running lean ? Has anyone else had this problem and know what to do? Thanks.
