No its not.

You sure about that ?

could it be that my standard fuel pressure regulator has failed because of the better flowing fuel pump?

and the tuner will find that out when he puts the pressure gauge on it.

yes i will leave it up to the tuner but id like to know also to problem solve for myself. narrow things down you know.

just want to know who has seen this sort of problem before or who has had it.

cheers

until 2 weeks ago i was missing 60 rwkws due to the ebc having no power feed to the solenoid.

so it looked like it was working when actually it wasnt.

the power feed to the solenoid also controls your idle up solenoid, so it can also effect your afr's

thats why i mentioned it

Could be a few things but, most will give other symptoms.

A loss of compression will slice power off, to some degree this can happen without appearing a massive smoke fest. Worth a quick compression and leak down test just to check overall engine health. A range of possibillities there.

The cam timing can possibly be at fault if the belt is stretched. If the belt has been changed but, not the idler and tensioner then this is possible. The shift in cam timing can cause a dip.

Small intake leaks. Check the pipes and clamps.

Intake pipe sucking closed. $5 fix for that one.

    • Waaay ahead of ya....(evil laugh!!) Will show the fitment and spec details later when it isnt as rainy !
    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
