I have a 99 with 275 injectors Practical Solutions boost module DTT transmission Rasp and a BD exhaust brake. Recently my VA box failed so I want to replace it with a Edge EZ. Questions ? the boost module need to come off right as the ez has one? I haul a 2500 lbs camper and 1500 -2000 lbs trailer sometimes. Will I have EGT issues? No gauges and really don,t think I need them?
