Really bad fuel cut..

[mazdasp33d]

Full corksport turboback exhaust and cp-e inlet and sri, pg fmic and a stage 2+ map etc. etc. Yes I know the weather plays a factor but now at wot for the past couple months my fuel PSI on my dash hawk has been <700. even less, when they should be >1600. I think my fuel internals are shot. Never had this problem before even last fall/winter time.

Low fuel pressure = bad fuel pump

From everything I've heard, that is the only reason for having low fuel pressure. Also, I guess anything less than 1400 psi at 60%+ throttle is considered no good.

I suggest the PTP unit...has worked well for me so far.

Depending on mods, you can GET AWAY WITH as low as 1400 but, technically 1669 is the target psi below which the pump is failed, according to Mazda.

700 is completely unnacceptable and highly dangerous. Lay off WOT and keep the rpms under 5k until you fix it.

No I know not to beat on it. I have been drivin like a grandma. It sucks. So now I guess to get some new internals

Mine's doing the same thing but, as long as I stay off WOT and under 5k I can still drive spiritedly enough for public roads. You don't have to drive it like there's eggs under the gas pedal. Just keep an eye on the DH and it'll probably show good pressure up to the 60% throttle load range.

The factory pump can't keep up with all those unrestrictive mods you have on there. Get yourself some PTP or other internalls before it decides to go on you.
