Please enhance the clarity of your questions.  Because whilst I can probably deal with the first one (the answer would be to turn the knob on your boost controller in the up or + direction!) I can't tell from your second question whether you changed the engine or changed the gearbag.

The answer to Q2 is the same answer as Q1, turn it to the + direction.

Cheap manual bleed valves have a problem where they will slowly lose boost response.

 

As always, be careful when changing boost and make sure your gauge is accurate.

    • And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.
    • Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.
    • I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.
    • Deeve, I don't suppose that you've made any progress on this? My Stagea has the exact same problem, and just like you, I've read through as much as I can online, with no real progress. My car isn't throwing any codes at all, which is a little frustrating. I've changed plugs, checked the wiring and harness. A new MAF gets here next week, but I'm not hopeful it will solve the issue.
    • I installed it all myself,  It was really easy to install.  I got a professional to do the degas/gas.
