planning on cleaning my throttle body today and i'm wondering if there's anything else i should do at the same time....
You won't need an upgrade till you do cam/heads/stroker.. and will not void warrenty unless they can prove that it was the cause of your engine failure,The question that I have is what are the performance gains with the different throttle body sizes and are there any negatives or this that could / might happen.
05-12 Dodge Hemi 5.7L/6.1L 85mm Throttle Body
05-12 Dodge Hemi 5.7L/6.1L 90mm Throttle Body
Plus will this void any warranty on the engine?
