In short, any pressure spike seen near/at the throttle body is not going to increase wear and tear of any parts in that region. The part you are trying to protect is the compressor wheel.

I agree, the only time that you see throttle body failures are on insanely high boost situations or in nitrous applications. That's why race builds, especially drag cars use aftermarket throttle bodies such as the Ross units.
