Adding Accufab throttle body on a turbo car require a new tune?

[98 svt]

I have a 98 Cobra with a 67mm turbo. I have a good safe tune, but my throttle is sticking around 1800-2000 RPMs pretty frequently. I have an Accufab single blade throttle body I want to throw on the car, and I'm wondering if I can safely do it without a new tune?
I'm assuming yes, but want to make sure.

Anyone with any insight?
My original plan was to throw it on before I went up to Pete at Performance Dyno for a final tune, but I'm curious if it will help with the hanging idle.
I've had to cancel my tune appointment with Pete twice due to family obligations that came up last minute, so I don't want to schedule a new appointment just yet.

You do not need to re-tune for a TB change. Just put it on and go drive it.

Thank you, good sir

When was your last tune at Pete's, Paul? Is it an interim tune? Curious because you mentioned you have to schedule final tune.
