its a 2004 5.7 hemi, when you punch the throttle it takes a second or two to respond. Been told by two service depts it is because of a electronic connection of the accelerator used now.. that the cable linkage was done away with.. is there a way to increase response time of acceleration ???? thanks

 

Buy a Superchips programmer. Should get rid of the lag, unless something is mechanically wrong, which I doubt.
