This thread is to give an idea to people with stocks cars what to expect when adding any type of performance hardware/software to increase engine output. We should list our mods and how many miles you have driven with those mods and any problems you've had. This should help most of us with making informed decisions. I'm piecing my kit together and would like to know what im getting into.
Also I think we can add suspesntion, it's nice to know how long shocks/struts last
for example:
2002 a4 1.8tq
56k miles, stock, blah blah blah....get the point.
