Say I have an 01-02 tahoe/suburban DBW setup (with 411 PCM), can I use just any larger size TB (like a 90mm) or any p&p TB? Will any DBW TB work with the rest of my dbw setup?

I ask because I have a motor/PCM/harness out of an 02 tahoe that is missing the tac module and pedal. I'm tryin to decide if I should just find the tac module and then upgrade the TB on down the road or if I should just get a bigger TB and matching components now.

PS - Sorry if this is in the wrong section...I thought it sounded like electrical....
