Starting work as a Flat Rate Tech this week

Alright guys. I'm not going to lie, I'm scared crapless:sad5:. I got hired at Firestone as a flat rate entry level tech. And I'm just that, an entry tech, I have a good idea of how to do my duties, I'm just not really fast yet.

Do any of you flat raters have any tips for me so that I can possibly earn a pay check?

Do you guys impact out most of your bolts (I know not in)? Or use an air ratchet?

Thanks!
Drake
