Diesel Bombers - Which Chip????

I have an 04 Cummins 3500. I previously had an Edge Attitude/Juice on it, but either the chip was F*d up or my injectors still are because it would frequently cause my check engine light to come on. Then the truck started dying while i was driving down the road. I check the check engine light, and it came up that the injectors were shorting out. I took out the Edge, and i havent had any more issues since then. Im hesitate to put the Edge back on because the same issue could still occur. I started to think about getting a smaller chip, like an Edge EVO HT, or a Smarty Jr. simply because i dont need all the power, nor do i want to spend the money again. Any suggestions on either the Edge EVO or the Smarty JR???

Should i be worried about putting another chip on with the same injectors that shorted out before? THANKS!
