Hey guys i need some opinions on this

I have an r32 gtst, its pretty stock engine wise just has a filter a cat back 3in and an early model safc,

its boosted to 14psi but it has a miss at full throttle (still has a miss even at stock boost), im pretty sure its not detonation, just a miss, i have changed the tps, afm, all the coils, and the cas, pretty much everything except the o2 sensor (because its fairly new) but it still does it, if i wind the fuel back slightly from stock it is better but still sometimes does it, its really annoying. Any good ideas anyone?

theyre s1 coilpacks, ive used them before on an rb20 they worked fine, i dont know if it changed dependng on engine temp cos dont thrash it when its cold and it never gets over normal operating temp, im sure its not the coils as this is the second set, i brought the timing back just slightly seems to be better, but i shouldnt have to retard it at all

      Mistakes were made, my R34 Story

      So I actually had the cover off my car today, here is a (bad) pic of the setup. I have an oil cooler thermostat block, the temp sender is straight in there. The pressure sender has a short AN line to a T piece which is mounted (hopefully cable tied counts as mounted....) on the chassis. BTW every fitting you could ever imagine exists....just depends what they cost and how many you need. Raceworx AN adapters are here: https://raceworks.com.au/fittings/adapters/, I think you said you need BSPT to AN (https://raceworks.com.au/fittings/adapters/bsp/tapered/an-to-bspt-adapters/) and AN to NPT (https://raceworks.com.au/fittings/adapters/npt/) BTW, braided line is super simple to make. It looks intimidating, is not.

      I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?

      Anyone running the VQ37VHR with forced induction?

      I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.
