i saw the Kelleners camshaft and software upgrade at and wondering if this $4k upgrade is worth it? does it really give you the gains it claims and if you do other upgrades will software adapt? what if you want to do a powerchip upgrade, can you do it? they claim 45 HP and 40 Torque gains. how hard would it be to install it yourself or how much would it be if you had a shop do the installation?
