Bad Ffp?
i'M HAVING ISSUES WITH MY FFP. wHEN I'M DRIVING AND I MASH DOWN ON THE GAS AT AROUND 4K MY CAR SLOWS DOWN DRASTICALLY. i'VE CHANGED OUT THE FFP A FEW TIMES. ANY OTHER IDEAS? i WANT TO GET AN ADJUSTABLE FFP BUT TALK ABOUT EXPENSIVE.

Ah! yes... fuel pressure regulator (FPR). Adjustable ones are cheap... it's the rising rate ones that are expensive (and not needed on a non-turbo motor). Why do you suspect the fpr? Have you tested the fuel pressure & a/f ratio at the time it loses power (aka fuel pressure & a/f gauges)?

so stumbling at above 4,000 rpm consistantly might be the AFM?
I'm having little issues but I wasn't going to worry about it until my wastegate gets fixed. 4300rpm submles every time under boost.
I'm still working on my A/F ratio gauge install

Well I'm not saying I'm sure that's the cause, just suggesting to Skittle (and in your case too) to check the fuel pressure & a/f ratio when it happens.

As Skittle said, its hard to check the fuel pressure on the rail when you're going 80mph, wide open throttle, in 3rd gear.
I also noticed last night that my plastic fuel injector holders are breaking apart! 7 months old and already destoryed. Maybe my injectors are backing out at that rpm? hmmmm.... I'll put new ones in when I replace the manifold gasket next week... after my Pulsar passes emissions!

A local Z'er said he just T'd the fuel line & ran the fuel gauge up to the windshield where he taped it so he could see the fuel pressure while driving. Sure... it might be a big ghetto, but it worked.

2 of my plastic fuel injector holder are breakin apart to... ill have to make do until i got money... but teh car aint running yet so i guess no big. lol those things are crappy though.... they should be like a urethane or some sort of solid rubber material...
and how would you get a HUG to display your FP guage though? lol....

BASTARD!!!! lol.... well its only 2... i can make do for now... i have my pallnet fuel rail just chillen (need an FPR) and my buddies DSM injectors... but i need a way to control them thats where im on a snag... cuase im BROKE!!!! lol... gotta get me a SAFC or a standalone... that or SAFC and then a method of eliminating the stupid AFM. but... the first challenge is getting it runnin. lol. and in the process making the motor shiney or at least presentable again.
if i start making money again i want an aeromotive FPR... adn i guess ill need a guage otherwise i wont know what its all set at.
