Guys,

May I know what's your opinion on this? What're the good & bad points for each of them? How much tuning points they've got? Just that GIAC and Revo ones have controller to select few mappings to choose from compared to APR. Pricing wise in here more or less the same.

Aside this, I have piggybag from Trust E-Manage blue from my previous ride. Can this be plugged-in to Polo?
