b&M fpr?
THe b&M fuel pressure regualtor is only a fp riser Correct. That would explain why when I set my fp to 43 at idle, the next day its at almost 70? This has happened numerous times. So if I get the aem unit, it should hold the fp to 43 at idle?
thanks

Re: b&M fpr? (b16ahybrid)
The B&M is nothing more than an adjusting device that clamps on top of the "STOCK" fpr to provide pressure adjustment "up and down". You need to cut the top off the stock fpr and clamp the B&M on, as well as replacing the internal pressure spring. It's NOT a fuel pressure riser that normally associate with other FMU that raises much higher fuel pressure proportional to boost. However, the stock fpr does increase fuel pressure slightly (approx. 1:1) bases on boost pressure.
