    APR Stage 1 vs AmD Tuning custom map?

    Opinions on APR Stage 1 map vs AmD tuning (Essex) custom stage 1? AmD used to supply APR but now only do their own maps. Does anyone have experience with their custom map? Both are same price more or less. I'm looking at stage 1 for my S5 B9 (354bph stock).
