We installed the AEM FPR and set it at 34psi. Well, over the last couple days it has steadily dropped to ~29.4psi. At start-up, it's a little higher, but has been very slowly but steadily dropping.

Also, starting the car is HORRIBLE. It stutters several times and finally cranks over weakly, when before it was an instant clean start. Also, the last time I put the key in and turned the battary on. (turn on gauges) FP only went to ~11psi then dropped back down to 0. WTF?

I don't feel safe boosting when the car is acting up like it is. Thanks in advanced for the help.

 

Sounds like a typical AEM product.

I'd try something else or run stock until you get that figured out.

 

Yeah, sorry to say, Craig, those are my thoughts, too.

 

yup, the general consensus over on HT is AEM FPRs = crap too!!!

 

You pu$$ies! I was waiting for someone else to SMACK him, but nobody replied.

So I finally reply and within 5mins. you guys jump in.

 

 

Thanks for the help guys.

It's not the FPR, or if it is, then it's one EXPENSIVE peice of ****. Sx7r and SeximaGTR are running it and have great things to say about it.

I guess I will have to readjust the FP back to 34psi. I heard sometimes new units take time to adjust into place, which makes sense.

 

the fpr is fine for me.... are you sure your locknut is tightened?

 

Locknut is tight, all lines are secure, elbow is secure, ect. Yet I still got about 6-7 bad stutters before the car kicked over. The FP rose to 34psi, but it was because my car was cold and it had a high idle. My fuel pump is fine, becuase up until the time of the FPR install my car started flawlessly. But then again, my FP used to rise to normal when turning the key to battery-on, but now it goes up a little and dies back down to 0psi.
