those are two cams indeed.
you do need mapping to make use of them.
my engine is currently At APR USA and they are building a Stage 4 for me.
the problem is that Schrick is out of stock so i needed to find someone who do have them in stock.
i have got permission from APR to post for the first time exactly what stage 4 includes, but i will do it once i get some pics.
i'm flying to the US tommorow , and i'll be at APR wendsday and also attend Aterfest saturday.
updates will come in a dedicated thread when i get back.
