found the trinity on sale today, I;m still in doubt about these programmers, still have the choice of the diablo predator as well locally

it seems there are about four different ones that keep getting recommended
diablo predator, smarty jr, Bully dog, hypertech

(some others as well I forget the name of)

but I really need a good answer,
I want to get a few more mpg, I want more low end power, I want to be able to adjust the trucks speedo for when I put taller tires on it very soon, I was told the diablo predator was good for between 4-8 mpg at the 50hp level, I will be opening up the exhaust some to(want to hear her a bit more)

so is that really true?4-8mpg? if so will the trinity do the same? it is really worth that much more to buy a trinity over the predator?

I have 4:10 diff, this is a 2006 ctd 4wd 4d dually 3500 auto trans

again, this is m 1st diesel truck, so I'm just a newb to this stuff, performance work for me was long ago on trucks,


thanks
Tom

 

Smarty is the best programmer on the market for the CR. 2-3 mpg is realistic.
