33 Gtr Running Weird

[#taylor#]

got a 33gtr with exhaust, arc cooler, pods and a evc 4 just put in. and running just under 1 bar.

was having a few issues with the boost dropping off before but now the evc is installed the boost doesnt drop off. the car will be running sweet but than it will just feel all sluggish and not go like it usually does. notice a big power loss

i've searched and read something about rich and retard and wondering if this would apply to the gtr also. cant think of anything else, just thinking this might be my problem.

any help would be great, thanks

If its running rich check all pipes for a boost leak.

If its running lean check all hoses for vacuum leak.

Does the problem fix itsalf when you restart the car, could be sensing detonation and dropping into the low octane map.

once you restart the car it fixes itself. cant hear it detonating and im only running .7 to .8 bar. everything is pretty much stock with a few breathing mods.

all the hoses are fine and everything is in order so no leaks anywhere.

if it is detuning itself as it feels like it is, how do you find out why and how would you fix the problem??

how is your EBC setup? got a pic or diagram of it?

Could also be your spark plugs. How old are they and what gap you running?

before it was cutting boost and running a bit sluggish but thought it was just a problem with the factory boost control. had restrictor removed on the standard boost control also.

so i replaced it with a ebc and now its boosting properly. ran new lines for everything so its setup properly.

the car will be whilest running low boost(.7bar) and than after a while it feels like it will detune, but still running same boost now i changed to a hks evc.

but happens almost staight away if running a higher boost(aprox bout .9 - 1 bar)

the plugs looked good when i got the car compression tested.

check all your vacuum hoses and i/c plumbing. do u run an aftermarket BOV, could be leaking. And also check the gap of your plugs
