valvebody upgrade

I would probably look into a speed density ecutek tune since I believe the maf readings get messed up with the stillen charger. Also would be nice if there was a way to but an iat sensor into the intake manifold for true after charger temp. I would just stress that your after safe and reliable and not big numbers (and of course Seb is always great).
