you will also need to keep money available for tuning the truck on a real dyno when done I took a power and performance class that used a Dodge Dakota Rt and no matter what you dothere is no getting around tuning the computer Chrysler computers are very state of the art compared to most other manufacturers and it will compensate everything and anything to make the stock parameters the factory programmed It with. even with a stand-alone ignition and a fuel control device it will still change the pulse width of the fuel injectors,even the duty cycle won't be as long, I have seen many people try to make performance with a lot of these computer controlled Chrysler's and fail from not getting them tuned. Not to mention also ruining their freshly built motor. a good tuning session will run about 800 dollars. it will make all the difference though, and it will also save your engine from major damage.
