Why does it have a boost leak? And what is so hard about solving it? And what is preventing you from bringing it to the dyno day? Does your car run?

It wouldn't be very hard for me to check the wiring. There's only one wire that has to be pulled out from the harness for XEDE installation. It's easy to confirm.

I checked all the hoses and changed the BOV with 3 different stock one's 2 forge ones and a Greddy. I put the car on a lift and checked all of the intercooler hoses as well. The problem is the 1st shop I took it too pulled out 2 of the wrong wires and I found one it was the idle wire and the other was a dead one I think # 16 or something. Then I used a meter and tracked from the boost control wire to the ecu and it got voltage when I tested it so I know I have the right one for boost control but as soon as I installed it I got a P0243 error and that was the 1st time this was hooked up because the shop had it hooked up to the incorrect wire. So now I have boost control a good idle, and a boost leak above 5500 RPM's it goes from 21-22ish and then at 5500 it drops to 13ish and you can hear a loud whoosh noise. A person that had a problem with a BOV said that was the problem but the odds of having 6 BOV's just does not add up. I don't want to ship the car out to you but right now I don't know what to do. You know any shops that can fix this in the southeast? Oh I also changed the boost control Solenoid.

 

I know you said you checked all the hoses but every time I've seen a leak like the one you described, I found the lower intercooler hose to be too loose. Needs to be cranked down pretty tight in order to keep all that boost contained. I have a hard time believing that all 3 BOVs are leaking-- especially in the way you are describing (above 5500rpm) so it's got to be a loose hose clamp.

Just my 2c

I will check all of them again, what about the P0243 error? Any ideas? Also you know of any good shops in the southeast?

 

Anything is possible with a boost leak. Get that fixed first and let's go from there...

Okay I will change all the hoses and tighten the **** out of the clamps tomorrow, I know someone who put the blue hoses on his car and I will use his stock old one's. You know the boost used to hold all the way to redline until I installed the turbo-back. Also Shiv thanks for the good support man!

 

Eric,

Must be a long movie. I PMd you a couple of times. Still waiting for map.

 

Shiv I got it fixed, it was the 2 clips on the airbox that hold the cold air duct on. They were missing and at high RPM it would suck the airbox to the hood. I am sure you will see some of these down the road. Also what is the cost and where is it? Any other spots open?

 

Okay, Shiv I talked with you a few days ago about how I screwed up my xede and you told me to test it lower all the boost values to 0 and see if the boost goes down. Well I just got back and the lowest I can get the values was to 50.2 across the whole table. It DID lower the boost though to about 12 PSI, I was getting 22-23ish before so I know boost control works. What's the next step?
