Hi
are the throttle bodies any different from the 6.0 vs the 5.3 v12?
thanks in advance

 

As far as tuning a large throttle body goes, an alpha-n tune will have weird afr trends and be difficult to make drivability smooth. It will feel like an on/off switch. A MAP based tune will have a very small pressure window that is controllable by the throttle blade, every thing else will be the max pressure at that rpm. That pressure is dictated by the plenum volume. You want your throttle body to have good Showbox jiofi.local.html tplinklogin control over plenum pressure, which is load in a MAP based tune.
