With the cost of fuel skyrocketing, I want to improve my mileage. A guy at Infiniti parts suggested Unichip. Any thoughts and recommendations?

Unichip is one of the ways to tune your engine but it won't improve your mileage. Your best bets are:

1) Increase tire pressure (less tire resistance)
2) Use cruise control (better throttle control)
3) Go easy on the accelerator
4) lower your fx (less wind resistance)
5) Go with a stock diameter exhaust (HKS Legamax or custom)
6) Get rid of the runflat tires if you have them

Tuning (Unichip, Emanage, Utec or Technosquare) can give you a better Air-Fuel ratio but it won't help much if you're not modded. Also, when tuning they generally increase timing which will reduce mileage..
 
Drop it, intake, exhaust and you're good to go. (probably +2 mpg with those 3)

At one point with the LMS supercharger I was getting 26-27 mpg highway (on stock compression)... but the cost of the charger will negate savings, and the lead foot will diminish savings.
 
my fx35 is completely stock. I run toyo tires on it properly inflated. What about a combo of CAI, exhaust and a unichip for better fuel economy? By the way I average 15.4mpg.

Again, unichip or any piggyback/ECU flash won't give you any significant mileage improvement. In fact, there's a good chance that it will reduce your mileage. As Cube said, if you want to mod it for mileage, do intake, exhaust and the drop. Also with any piggyback, you're looking at at least $1000 expenditure with the product, installation and tuning. Consider that as well..

Best way to increase fuel mileage is to ease off on the gas, period. Don't gun it from a stop, ALWAYS cruise at 65-70mph and do not do any high speed passing. With this I went from 13mpg to 17.5mpg on my 45 with a 75%/25% mixed highway/city driving.
 
By Far, the best way to save gas is not to drive short distances. My drive to work is a total of 2 big miles. With that, I average 12.5 mpg :err: & that's not with a lead foot!

+1 on all.. I went from 12 to 16 75% city, 25% hwy.. Doc, 17.5 mpg is amazing for the 45!
 
Yea, Ege I know but i feel like a pace car, lol. The 91 premium gas was/is a killer. But at least I went from filling up every 3rd day to every 5th day now.

Just did a minor installation today trying out an experiment, will see how much better or worse the mpg gets.
 
that's right! the best way to save gas is to maintain the pedal constant trying to avoid high RPM always, trying to keep all the gears not more over 2100rpm. and obviously on highway do not exceed the 65MPH.

if you staying over 65MPH, you gas mileage decrease over 20%.
for example beyond 80MPH.

I've started with the Stillen CAI. I haven't received it yet. I'll hold off on the catback exhaust for now. It's $1200 vs $250 for the CAI. I use my FX35 for work. Month in and month out I average 15.4mpg. I normally burn premium. When gas went over $4 pg I switched to regular. My mileage is exactly the same. I do drive normally getting this mileage, as in, not a lead foot. How do you get the mods to show up on messages?
