Message Ok, I have owned my Z32 TT for 3 years. Ever since I put in a JWT stage 3 ecu, and boost jets into my car I have a really wierd problem with the boost pressure.
First of all, I have never put my car under full boost before it has completely warmed up. After I installed the ecu, my car would not even boost as much as it did stock (about 8lbs). So I turned it off, started it back up and then it would push between 14-15lbs (Which after the ecu and boost jets, is where it should have been). So,... I accepted the issue and just did that every time I drove my car.
Now, I have just brought it back out after the Cleveland, OH winter only to find that my car is idleing smooth at about 1300 rpm's and not boosting as it should, (about 8lbs on the oem boost guage). If i turn it off after it has warmed up as I had done in the past, it will boost for 1st gear and then go back to about 8lbs.
Does any one who knows what there talking about know what could possibly be happening? !Thanks in advance!
