General Skyline Discussion / Re: R34 GTT Boost Issues

Hi, Did you get anywhere with this, i would have said it was either a check valve, lines or the boost controller being the issue

My tuner has the same EBC on his GTR and he has confirmed that it is wired correctly. We even replaced all of the silicon hoses with rubber hoses and ran them out of the bonnet and through the window (instead of through the firewall) to avoid crimping.
We tried countless settings on the EBC and nothing would change boost levels. We even tried another Greddy spec II EBC that we knew was working and still had the same problem.
My tuner is leaning towards an earthing issue so when I get some free time I'll go over all my earthing points to make sure they have a solid connection.

Thank you for your reply. Any help is hugely appreciated!

General Skyline Discussion / R34 GTT Boost Issues
« Last post by Beached on October 29, 2018, 10:03:14 PM »
OK so early this month I went to get my r34 tuned from a reputable tuner.
The tune was going well until we ran into a problem. We couldn't make anymore boost than what the wastegate actuator was set to (10psi).
We tested out a different EBC and still had the same problem so we thought that the problem was the wastegate actuator.
We tested a boost tap and got 22psi so we ruled out the actuator so we thought it was the boost solenoid valve.

The next day I bought a brand new mac 3 port boost valve and put tested it out on my car. I also raised the preload on my wastegate spring.
Drove down the street and got up to 18psi so I thought the problem was fixed and booked another date for my car at the tuners.
While I waited for my tune I turned my EBC off in hopes that I wouldn't over boost although I was still making upwards of 17PSI even though I was "never" using WOT.

Then I bring my car back to get tuned thinking that the problem had been fixed but on the first run its stuck on 11psi.
We tried changing relevant vac lines with new hoses.
We made sure that the new boost solenoid is operational.
We put pressure onto the internal gate via a compressor to make sure it wasn't flapping open prematurely.
But we couldn't figure it out so I ended up leaving gaining 1 pound of boost..

On the drive home I went to a long straight private road and in fourth gear with the EBC off I made 16psi @ 5500 rpm..

Any clue as to why my car wont make boost on the dyno but it will on the road?

My mods are as follows..
RB25DET NEO
Pod Filter W/ 3" intake pipe
R35 GTR MAF
Highflowed OP6 Holset recore w/ R32 GTST 10PSI actuator
FMIC
Deatchwerks 320lph Fuel Pump
Sard FPR
650CC FIC Injectors
Greddy PRofec B-spec II EBC
Splitfire coils
3" exhaust
Nistune type 4 daughter board

Any help would be much appreciated! next step will be changing the actuator to 18psi and removing the EBC..

Thanks. I'm not sure if any cut/ weld suspension components can be certed. Saying that, Gktech has a full bolt in knuckle. Not cut and shut. But there are certain guidelines about altering suspension geometry in the cert process, I'm sure. But for me, drift knuckle set up / angle mods is a track only mod.
