Yep you pointed out an error in my arithmetic and you are correct, 150% more fuel mileage than the current 44% above I am getting is 250%, I made a mistake, I just wanted to see if i could get it up to 70mpg's. my main reason is to test all of the mods I have heard about on this website, and give my opinion about each in detail, and the percentage of gain. I have alot of study time in automotive performance parts, and the claims for improved mileage. But just telling someone that it works or not especially on this website is obviously not good enough. Having been a mechanic for many years doesnt seem to matter to most. having been trained to diagnose poor fuel economy and runnability doesnt matter to everyone either. Arguing about some peoples internet knowledge is exhausting, there is so much incorrect information out there it is astounding.

No, my point of my bullet pointed list was completely missed. You must evaluate all of these things on your car that you have chosen to mod. If you have chosen to mod a 1978 Buick, taking into consideration the fact of the vehicles condition of parts and runnability will develop a baseline for starting ecomodding with it. If I would have said trying to mod a car like that is pointless, I would have started a fight. Because I see no difference between you wanting to mod that car and wanting to mod a 2005 Dodge Ram pickup getting the same 12mpg and 20 inch tires. I think working to achieve 5mpg better is a substantial goal for a v8. Dont you think that if you go to the doctor describing feeling like crap and having no energy, and you have been drinking, smoking, and having high cholesterol for the past 20 years, is he or she really going to give you the best advice when if he or she was trying to answer your question "doc how much life do i have left"? The starting point of that idea is almost ridiculous. But, I would believe if you corrected the starting point of the idea to get either yourself or your vehicle in optimum condition before the ecomodding or asking the question how much time do you have left, I think the results would prove in your favor.

"the shortened version"
My list means get the car, (any car) in optimum working condition before you mod to get the best results. My list is just a portion of what I have considered on my project to get optimum results. If you did not do that, are you really going to achieve the results you are looking for?
