Electronic Boost Controller causing spike?
Although I don't drive a Honda, I figure that some other turbo cars may experience the same problem that I am experiencing.
My car (200sx Se-r) is equipped with a t3/t04e (.50 trim, stage III wheel) turbo with an internal wastegate. I am using an AVC-R boost controller to handle the boost.
The problem I am experiencing is that whenever the vacuum lines for the boost controller are hooked to the turbo, no matter what boost level it is at, it spikes dramatically. Example: a boost spike when set at 10 psi, goes to 15 psi. No matter the weather, hot or cold.
When the vacuum lines are unhooked, I only experience creep when it is extremely cold. I ordered the GReddy T.V.V.C manual boost controller last night hoping that it will no longer spike.
Will this be a good solution or should I upgrade to a stronger wastegate actuator? HKS sells one, and I just don't have the money to upgrade to a new manifold, external wastegate and different intercooler piping.
Thanks for any input.

Re: Electronic Boost Controller causing spike? (2LiterTurboSeR)
Internal wastegates are known for creeping and spiking. I had pretty bad problems with mine when trying to boost over 10psi. I recently got a tial external wastegate and I no longer have any spiking or creeping problems.

Right now, I'm using a BlueBird manifold, which is a factory Nissan manifold from the JDM SR20det (FWD). Unfortunately, this manifold has a different configuration from aftermarket manifolds, which mount the turbo on top of the manifold. My manifold isn't configured for external wastegate either, and I am damn broke.
I was reading on another website that HKS makes an upgraded internal wastegate that is supposedly stronger than the original wastegates the turbos come with. Can anyone verify this?
