Alright. With my shadow back up and running, I'm still suffering massive boost creep.
My turbo setup is this. A TU super60 turbo with large wastegate can, 63 A/R housing, TU 3in swingvalve and full 3in exhaust. I have a 3in exhaust cutout as well.
Boost control is a HKS EVC EZ, along with direct vacuum line to wastegate. When the car was down, I also ported the wastegate hole abit. Just not anywhere near the diameter of the TU's puck. I openned it up and smoothed the transtions around the hole.
Either with the boost controller turned off or direct vacuum line to manifold, the symptoms are the same. Low RPMs, I get 9lbs of boost at WOT. My boost creeps up fast as I cross 4000 RPM to redline. Boost shoots to 14lbs of boost by redline.
What can I do in the short time to help lesson the boost creep. In the long term, I still have to install the new block. At that time, I'll probably port the wastegate hole more.
My thread about porting the wastegate hole.
