On my R33 Gts-t S2, I have just installed a FMIC, turbosmart BOV, and a turbosmart Dual stage boost controller. Apart from that my car is standard

on the low setting its wont go below 9psi. and on high it is 11psi

i want low to be &-8 psi but the tap wont go lower.

is this due to wrong installation or a boost creep

I can't help you if your answer to my question is 'The standard way'.

The vacuum hose from the controller should be connected to a T-piece. The T-piece should have an arrow on it. The arrow must point to the vac hose that connects to the actuator. The other side of the T-piece needs to connect to the pressure nipple on the intercooler piping that comes from the top of the turbo.

If you have it connected to the wrong nipple (there are 2) then it will not work. Also make sure you have disconnected the solenoid that is beside the power steer res.

      some days eh? The keyless entry and interior light on/off with the key will be controlled by the Body Control Module, but I'm not certain where that is or what it looks like (you might get lucky with a search to get a part#, which could be printed on it). I'd start at the A pillar/ Under dash/kick panel on the driver's side

      It might be hit and miss, but Nissan Genuine Parts and Pitworks are not the same thing, although both are available from Nissan Dealers with Nissan Part Numbers. Nissan Genuine Parts are the OEM stuff, Pitworks are their attempt to get people back from generic parts makers

      I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.

      Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too.
