And meth on or off no difference right also how do your plugs look and what type of inlets and outlets you run. I know everyone argues that the turbos y into one but just the change in exhaust restriction can have an effect. I have bunch spare parts if you need anything let me know theirs good chance I might have.

Just to bump this thread. I had the same issue and replaced the VC and it fixed my STFT issue.
