Mopar performance sells upgraded ECUs and so does Hughes engineering. Personally, Im going with the hughes because they can tailor it for what you have and what you want. You send them yours and they send you a tuned one.
Im going with a dual plane edelbrock, the injectors and exhuast with the ECU. Next year Ill pull the thing and have all the machine work done since it's pushing 200K. I really want the engine to hit 400HP on the dyno. That puts it about 320 at the wheels (20%loss) and I think I can hit about 420 tq at just over 2300 rpm. Perfect for wheeling. My axles won't live long after that but their destruction will be accompanied by the glorious sound of HP.
