What to ask?

[Laminge]

I have noticed over the last several years, people tend to complain that once they have spent dollars on their car, all hell breaks loose when something goes wrong.

I have been there, with my EB, strapped on a vortech and everything went to hell, if only!

So my quest is to determine what questions do you think should be asked at the time of initial discussions, should we actually arm ourselves with a check list and have the mechanic in question sign it off?

There are probably a couple of different topics or modifications groups you could lump it into, so I would be interested in your thoughts on

Supercharges
Turbos
Exhausts
Tyres and Rims
Cam Work
Basic Mods

I suppose some of the most basic questions are

What effect with this mod have on my warranty and what do you as my mechanic cover?
What development has gone into this product and what are the power gains?
Do you provide a before and after Dyno?
What after care should I expect?
Have you heard of the Australian Ford Forums and why are you not a sponsor?
etc
