How does the tuner help MPG? Are there drawbacks?you can gain MPG and power with a good programmer and i myself have done the math and with average gains of MPGs from people on here a bullydog gt will get paid for in gas savings in under a year then after that is like $300ish buck a year that is staying in your pocket.
to be honest i don't know exactly what all they are changing about your factory tune that equals more power and fuel economy but i've seen many members here claiming between 2 and 4 mpg from them. i don't have a tuner (having a baby in like 2 weeks ish and my pregnant old lady scares me too much to try and justify buying one lol) but i've looking into the bullydog gt alot and like most of the other tuners it has a tune specific for the best fuel economy at 87 octane fuel along with various tow and performance tunes and it also has what is called a driving coach that tells you when you are driving inefficiently and tells to how much energy your wasting and how to drive more economically. someone else on here might know a little more about tuners specifically and what combination of changes to your tune they use to squeeze out more mpg. and if you do going looking at the bully dog gt on their site don't let the price there scare you cause scott at fontana nissan can get you a very good price on one shipped to your door, i just wish i could take advantage of it too but getting stuff for the little crumb snatcher on the way is priority for me lolHow does the tuner help MPG?

If you were going to get a CAI with the main goal of increased MPG which one would you get?[/QUOTEfrom my experience which is mainly in Jeeps and sport import cars, CAI are designed to force colder air into the engine to gain hp and tq. Not so much MPG. I would buy a Cortex from one of the guys selling em in the classifieds. Support are fellow bros since they support us with tons of great advice. W/ a ecu programmer you can adjust your vehicle to the octane u want to use, so if you drop to the 87 oct u will be saving right at the pump. They also allow u to gain hp,tq and and an increase of MPG which is your main concern. For the money your gonna spend this is the way I eel u will get the desired results. I run 93 OCT w/ mine, got noticable diffrences (INCREASE POSITIVE) in all 3 field. Thats my 2 cents and the best $$$ I spend as far as performance for my truck. Thanks to the great guys on this forums advice and experience. Hope it helps and other i am sure will be able to chime in on their opinions as well that are more experienced in the frontier field. This is my first frontier but modified many a vehicle for different purposes based on customer request. GOOD LUCK BRO and keep us updated
