I recently purchased TTA 537. It has some mods to it such as a an atr downpipe with external WG, larger tb, accufab plenum, bigger injectors, larger turbo and an ans boost controller. I believe most of the work was done years ago and the car had little use.
Anyway, I have been staying out of boost mostly because something is not right. When you get going and boost builds, it keeps goin until almost 20 and starts breaking up. I immediately let out to hopefully avoid serious damage. I can turn the boost controller down, but it still happens.
I ordered a new coil and a silicon vacuum line kit. I will install them.as soon as they come in. But, I have read the atr waste gate is crap. Could the over boost be due to a stuck gate?
Should I just replace it? If so, will either of these work and which would be better for me

I'm not.looking to run that high of boost because I don't really want to run meth. Just want it to run properly and be safe.
