Oh sorry, didn't see your post.

You can with a Rising Rate FPR, but even then it's to about 8500-8700 rpms. Then it ECU starts to pull timing in the absence of fuel. So you really don't gain the HP you should, but you keep your 9k redline.

Without the FMU you will only see 5-5.5 psi before the injectors are maxed out.

Thanks guys, I will most likely go with a set of RC 550cc injectors, a 7lb pulley, and the Greddy E-Manage ultimate, along with an AEM FPR to compliment my 255lph pump, then I will make an appointment with Giles for a conservative tune. I only expect 300whp but if I get more then I will be very satisfied.

Pass emissions in MA? Let me know how that turns out, I may be moving there in a few years. The 550's won't hurt you. Ran stock injectors until I went to 10 psi.

I'll keep you posted, but in a few years a lot can change.
