If you can hear the pinging then you are in trouble, light pinging is impossible to hear from the drivers seat. If you only turn the boost down until you cant hear it then you may still be doing damage.

Get it on a dyno and do a power run. See if its pinging and then reduce the boost a touch until it stops.

If you retard the timing by messing with the crank angle sensor then response will be affected.

There is only 1 solution and that is turn down the boost. Otherwise get a bigger frontmount, bigger turbo so it can push the same amount of air in at a lower temperature and a computer so you can have advanced timing where you need it to maintain response and retard it on boost to avoid ping

      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.

      Ogura orc1000f vs Osg tr2cd vs Osg r3c experiences, max torque/max hp?

      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.

      Yet another RB Neo misfiring thread after reading all the others.

      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.
