hey guys I know what your gonna say... but I did my research on here and can't get a clear answer because everyone is argueing with eachother. Gas prices are insane here in D.C. I need simple mods that will increase my mpg and maybe increase my hp. So far I hear doing the exhaust and intake will increase mpg and hp. I need specific details on which to get, etc. Most of us don't know what to do. And by simple mods, I mean seeing a goodbreak even point with gas savings and cost for mod.
Thanks, no argueing. Need Expert answers.

When I added my FRPP Exhaust kit (http://www.fordracingparts.com/parts...tKeyField=9910) and drove home with it I got around 28 MPG (from 21~22) on 89 Octane (around 30ish miles on highway and city including 5 stop signs). Of course, naturally it declined but as the tank get empty, it slowly rises towards 28 again (considering the weight of the gasoline on a full tank). Which is another factor in it. Don't buy a full tank of gas because you are carrying extra weight with you that you don't need. Back on topic though, I average about 24~+ MPG not including the increase as it gets closer to empty. Although, the FRPP V6 Kit maybe a little pricer than others, but it seems to sound the best in my opinion (if your looking for sound and looks as a bonus ).
Another thing would be a CAI/Tune. VMPTuning.com even has a MPG Tune that may be of interest to you. I haven't gotten mine yet, but will in the next future along with 2 performance tunes to fill the other spots on the tuner.
Thats all I can think of right now! Hope this helped a little.
Some simple suggestions that can be had cheap and are normal maintenance type items:
[ul][*]keep your tires fully inflated to their max spec psi.[*]Change your engine, trans & rear lubes to full synthetic.[*]Add a GT take off muffler and a free flow air filter. If a CAI isn't in the budget try a GT airbox cover for added flow.
Personally I wasn't that impressed with my mileage tune this winter. Could be that the snows and winter gas offset the imrovement but I was getting no better then my perf tunes.
I have only one tank down with my new FRPP duals but have seen an improvement of 2 mpg highway. I still had the snows on but did install the 87 perf tune. Plus I have been leaving earlier to work so I don't need to speed. I'll have 1 more tank burned before I take off the snows so I'll have a better idea if the exhaust has helped then.
Hey Neal, if you really want to improve your gas mileage, sell the car. If not that extreme, install a set of 4.10 gears and T-Lok, always making sure to leave at least a 30 foot set of dual tire tracks when the light turns green. If not this, the mods the guys have mentioned work well too. By the way, if that's your f***ed up car in the photo, I definitely wood suggest getting rid of it. From the way it looks, it'll get the best gas mileage on the website cause it'll never move. Take care, Jack.
A CAI is a cold air intake. Most will require tunes, although there are a couple that don't. Cost varies. Most places will sell a CAI and tuner package for about $500+ again depending on the tuner and CAI. Also keep in mind that some tunes require higher octane gas. I think the mpg gains are minimal but I suppose theycan add up with mods. Most people say they lose mpgs becausethey're more likely to punch the gas a little more to fully appreciate their cars' new performance....I'm a relatively new Mustang owner and the only performance mod I've done is the single GT takeoff exhaust. The first tank of gas, I did notice a small increase of +1-2 mpgs. The next time I went back to what I was before becuase I found myself revving the engine a lot more just to hear the sound....So mpgs will just depend on how you drive as other have noted...
If your car has more than 15K miles, then I recommend that you replace your fuel filter. Gas these days is cruddy, and I replace mine every 15K. At 30K miles now, both times the old filter was plugged up & difficult to blow through. I would think that affects MPG (I know it can affect HP - just ask Boss244).
