here is the problem. the smoke is blueish white, it only happens when i do a run and then let off the throttle and then it is only a large puff and dose not really stick around. It dose not smoke at idle only when full boost/ high rpm. now i searched and found out that it could be the pcv, turbo seals, the eninge it self. any others that i am missing? the eninge has about 20k on it. it is a street port done by the pervious owner. also i am getting some weird symtoms with the car going into limp mode. it will not always do it some times it is fine others it goes right into limp mode. the idle is good some times and not others. the vaucum is sometimes at 14 and others 18. the gauge is rock soild at what ever number it is at. i have the following done, full 3 inch exhaust, intake, gold box , non-seq, and street port. this all of a sudden happened, one day the enigne died out of the blue and now all this stuff is going on. could this have to do with the gold box? put the stock ecu by it self and everything idle is alittle better. any help would be great to get me pointed in the right direction. i am a ASE cerdifited tech so this stuff is not new to me, but i am a nissan guy and am just learning about the 7.

 

if you know you are in limp mode what are the codes?

 

from the gold box i am getting Invalid EEPROM checksum, and Spark output fault. and if unhook the gold box i get codes: 30(solenoid valve-split air bypass) 33(solenoid valve-port air bypass) 34(solenoid valve-idle speed control) 38(solenoid valve-accelerated warm-up system) 39(solenoid valve-relief 2). the car dose not go in to limp mode with the gold box unpluggled, it only dose it when the box is hooked up.

 

When a FD smokes blue I have read that its most likely the turbos going bad. Gold box your referring to the HKS twin power?

 

no it is the peter feral system, a piggy back computer.

 

bump. dose anyone think that the gold box it doing all this **** to my car?

 

yes. the stock ecu fault codes may be real. do you have them disconnected? i say its the box

 

yes i do have them disconnected but i have restiors in there place, do you think that the restiors are bad?
