Remove Throttle-Body Ground before oil-change?

[CajunGreek]

My 3 goes in tomorrow for an oil change. Between the last one and this one I did the throttle-body ground and, being very protective of the warranty, am wondering if I should take it out before heading to the dealership. Anybody had a dealership ask them about or note the TBG when their 3 went in for routine service?

forget about it, they'll never see it, or care if they do

it won't harm anything

They didn't say a word.

Thanks.

Thanks.

I know this may not be the right thread to ask this, but the fact that the dealership didnt care affects my decision...

Does the TB ground actually do anything? Is there a noticibile difference in a close to stock mazda 3? (only sri added)
