Thank you, this is why I am asking.
i'll give another example of this...when i bought my truck, i almost immediately got a K&N filter. was it because my factory was dirty? no, it was because i believe that is a better than factory item that didnt cost me an arm and a leg to manage...
if a tune is $2000.00 the answer is, 'No thank you.' but if it is a couple hundred and i can get more power and better gas mileage (utopia, right?) then i can easily justify it...as you said Marty, it might not be a straight dollar for dollar savings, but if the truck just runs better, its a win.
i'll use this last analogy and see if this helps...you go to a doc, he says you need to restrict your diet...stop eating salt...and he gives you 3 things to eat (that tastes like cardboard)...and you ask the doc, as long as i dont eat salt can i eat more than this? he says sure...but dont eat salt...and you go out and find decent tasting food...you feel better, and you are probably healthier than just eating cardboard...(i went off on a tangent there, but i hope that makes sense)...i'm not looking for steroids, just maybe healthy food for my truck...
