Agree with Dave. I ran into problems at 10 psi. I kept on getting a FI light with the stock injectors. I switched to the S2000's and really like them. I have no low speed issues at all with them. The FI light is gone also. If you stay at 8 psi of boost the stock injectors will be fine. If you decide to go with the s2000's and 10 psi of boost I have a great map I will email you to get you close till the dyno.
