Hi,
I just bought this 94 Miata with Garrett turbo. The car runs perfect and I just changed the sparks and wires. However, when I floor it to redline or brake boost it, I always felt something like a boost creep. And the gauge shows there were way too much boost. It is tuned for 10psi but reaches 15psi! I looked up and thought it could be the high exhaust flow and port the wastegate should fix it? It’s my first Miata and I still have much to learn so I’m probably wrong. Please share your experience and advice. Thanks!

I also posted the video of my gauge recorded by my passenger( apologize for the shake)

you need to port the wastegate, just use a dremel and tungsten carbide bits, you can find videos on youtube or more info here...
