I guess since its pretty much going to be a DD and a fishing/hunting vehicle I'm not too worried about it making crazy gains. Just a little bit extra to catch a ricer off gaurd would be cool.
The predator from what I can tell allows you to tune in a way similar to Link (probably not nearly as well), adjusting fuel, timing ect.The others don't appear to have that ability. So you could swap out the injectors for srt4 stuff. That would be kind of nice if a person was to S/C it or run a bottle. I will have to call around and see what DB and the others say to run.
What they get out of a diesel with a handheld tuner is kind of nuts IMO. I almost think the manufacturers should hold their heads in shame for allowing such power to go untapped. But I suppose giving any Joe blow that kind of power equals a major Fail somehow.
