OK, I've been doing a little research on the forums about different aspects of my swap once its done and in the tuning stages. I have a stock turbo setup with a profec boost controller. I also have the Sard AFPR. I saw in one post that the fuel pressure must go up 1 psi with a 1 psi rise in boost. Originally I was going to pruchase the S-AFC II and still might purchase that particular setup. However, I also may be able to obtain a Mine's tuned ECU. My questions are as follows; First, what PSI must be used for the fuel pressure if my turbo is set at 10-11 PSI? Second, Is a lightly tuned (stock turbo, stock injectors, previously used with intake, muffler, and boost controller) Mine's ECU OK to run with an intake, turbo-back, and boost controller? I know the turbo back gives more flow and I plan to run w/o a cat as well. Finally, please give me your experiences with these items if you have them or have had them in the past. I figured that 10-11 PSI was obtainable boost, but please post any problems that you have had with that sort of boost (if any). Thanks in advance.

Come on man searchhhhhhhhhhhhhhhhhh.!!!!!!!!!!!!! This has been covered hundreds of times. The stock FPR rises 1 psi per pound of boost already and so does the nismo one, hopefully so does your Sard. Stock intercooler is holding you to 9-10 psi max though.
