im getting a sbd group n ecu kit[mbe]which will replace the afm and hopefully give me more power and better throttle response,on my 2.0xe.what i want to know is if i could put some hotter cams in,as i think sbd can deepen the piston pockets on std pistons by 2mm- i think! im also getting sbd's type a manifold,and a jp exhaust,the head sent off to v-tuning for a little headwork-what kind of power/torque gains can i expect from this lot.
