I have a Greddy Profec B spec 2 intalled for 2 weeks so far, and because I am going to put the vishnu XEDE in, I took it out yesterday night... and...

basically I hook back up the stock solenoid - with one line (the one that is closer to the battery) that goes into the intake pipe, and the other one (that splits into 2) to the turbo and the wastegate. Somehow I am only getting a 0.8bar of boost, which is a little less than 13 psi. I went back to redo all the lines again, and made sure they are no leaks, no puntures etc but still getting only 13 psi. I even took out the boost gauge line at the fuel pressure regulator because i was suspecting it might leak there, but still drives slow.

Anyone has any idea what my problem is? took out the profec b and then only 13 psi? Any help is greatly appreciated.

Did you reset the ecu.

 

Yes I did. The battery was unplugged for a good half an hour.
what else could it be?

How did it run with the setup? LOL sorry i just wanted to get that boost controller.

 

It ran fine and holds boost steady at 19psi. if you want it I can have it $300 shipped to you assuming you are in the lower 48 states

However, my problem is still not solved...

Did you remember that the turbo compressor hose and wastegate actuator hose are tapped to a T before it goes to the solenoid?
Hope this helps

 

Yes I did that....

Seems to me that the Profec wasn't working, maybe 275 and I might take it. How would I go to the money exchange?

 

People say it runs low boost if u dont out the restrictor that was in the factory hose back in. Plus it should be the in when u put the EBC on

 

Any updates on this problem? My car is also in limp mode. I'm only boosting .8 BAR

 

so, any solutions, i am also a gimp in limpmode... ?!?

 

Hmmm, has everyone with the boost problem taken out the BSC restrictor out?? In my eclipse I had the Profec-B with the restriction out and hand no problems with boost, I was running constant 18#'s, I know our Evo's run more, but not sure if this is the problem. Are you sure you have no leaks an any of the hoses or all your connections tight?.............thinkin..................

 

no, apparently after spending the last two days at the dealership... the solenoid is becoming a big problem and has been failing on evos, the techs have been getting calls about it left and right.. so now i have to wait 90 days! until i can get the boost solenoid, because it is in japan.. until then i will be running a measily 10# of boost!! this f*cking sucks!
