1992 Dodge Dakota 5.2 Magnum advice

Hey everyone. Im looking for some advice on what to do with my 1992 Dodge Dakota with a 5.2 Mag. Its a regular cab short bed with a 3.92 suregrip rear and a auto o/d tranny. Im actually shocked at how quick this truck is for being stock! I had a new 1999 Dakota RT 5.9 and this truck is alot faster! Im guessing the weight difference? Anyway what would be some good mods to do to this motor? Should I get the Mopar Performance ECU? Bigger throttle body? Different intake or work the stock one over? I plan on putting a 180 degree thermostat in it next weekend and I am also having the exhaust done. No cat and a performance muffler at this time, in the future I will be running true dual exhaust. Going to run the stock manifolds seems how they are the 92's. Would I gain any more power if I was just to convert it over to carb? Or should I keep the efi setup? My goal is to get into the 13's eventually. Thanks for any suggestions!
