What kind of gains can I expect?

I have a Superchips 1805 programmer, and I'm very disappointed in the mileage, I was getting 15.5 stock (hand calculated) with the programmer, one tank I would get 15.7 the next tank 17.2, next tank back down to mid 15's. If I do the DIY intake and a 4 or 5" exhaust what kind of mileage increase can I expect? I know with the cold weather here the mileage wont be great but when it warms up I'd be happy if I could keep a consistent 18 mpg, is that expecting too much?

I also have code p1248: Turbo boost pressure not detected. Not sure what causes that but could that be bringing my mileage down too?

MAP sensor reads boost...could be the tuner or a bad MAP or wires..

loose the SC and get a custom tune.. exhaust wont do anything really but make noise and lower EGTs a hair.. cut your stock muffler off your good for 400HP

17-18 might be in your grasp.keep it under 65 miles an hr

Yeah I wish.

Im not really looking for a bunch of noise, for exhaust I was thinking the Flowmaster Hushpower 4" turbo back. Intake I'll make myself. Would custom tunes REALLY be better than what I have? I never and I really mean never race my truck, hell I dont even take off fast from a stop light ( im 25 but I drive like I'm 75), so performance tunes are not going to do me any good, but if the tuners have better econ tunes Im all for it. I tow maybe once per year and its usually less than 5,000lbs, haul up to 1,000 2 or three times per year, truck came with a plow that I've used once, didnt really need to, only had 3" but I wanted to play. I might be selling the plow so I might not even have to worry about plowing next year. Are there any tunes that I would benefit from?

Sorry for the long post

First things first.... Do not and i mean Dont ever feel bad for writing a long post, i actual prefer it, the more info i get from you the better i can help adress the problem..

The 4" system will do nothing more then your stock will do without a muffler, the egts may be down a notch but that is it, power wise youll never see the benefits of 4" until over 400 hp lol The 4" will be noisy

Im 26 and trust me..i drive like a saint most the time but i like power haha, the custom tunes have better tranny shifting and better econ modes..now if you just leave it in econ all the time and baby your truck..just keep the super chips, but id still opt for custom tunes before anything else.
