Honestly,

I am not entirely concerned about MPG, I bought my 2015 Black on Black 370z cuz its a bad car :) !!

Thing is, my buddy is trying to get me to install upgrades like cold air intakes as well as a new exhaust system.. Quite unnecessary, but why not? LOL

I like to value my spending, so I figure if I get em, might as well have some return. Its not like I will be taking my baby to the track frequently nor will I be street drag racing anyone. The car handles like a beauty and I go to work in style..!

(Car can be a little quieter. Found a DYI thread on decreasing cabin noise - might be the first realistic 'upgrade')

:iagree:

:icon18::icon18: why stop there?? take out the sub, radio, speakers, passenger seat, power options, AC system, replace 19" with 18" wheels

if you figure this out, let me know how it's done.

is this your car or your buddy's car? why are you letting others dictate on modding your car?

also, decreasing cabin noise would defeat the purpose of making your car lighter and would make your car heavier, thus you wouldn't be able to save on gas.

You are not incorrect :)

1: The best thing for MPG is "adjusting the nut behind the wheel".
2: Prepare yourself for the most boring driving experience in the world, 'steady state'; once at speed your goal is to feel zero acceleration/deceleration unless you're going up / down hill. Cruise control will be a wildly exciting ride in comparison to trying to maintain momentum rather than a select set speed.

[before you all vote me off the forum I have burnt through 3 full gas tanks in a single day during track sessions, (75 laps around Sebring), in my 350z, my wife has a Prius and the driving 'excitement' there is a 'trying to reach 60mpg' video game]

3: accelerating from a stop, the 4 secs of fun, it's most efficient to briskly (75-80% throttle) accelerate, [but don't floor it the engine then goes into 'dump fuel in' mode] until you get to your goal i.e. Limit(L) +5, then just enough throttle to just begin the slowest coast to a stop you can manage, I let the speed wander from L+5 down L going up hills to 'L+5' +5 going down hills, the 350 was a MT so clutch in coasting was a plus, I've read shifting the AT to neutral to coast is a no-no for tranni longevity

4: look ahead, plan your stopping from 1/2 mile out to start your slow momentum loss, braking the final 5mph just as you reach the stop line, if multi cars are needing to get thru a stop sign in front of you coast and make a larger gap trying to time your actual stop at the sign just as the car directly in front of you is finally pulling away

i, luckily?, have an early commute so have little traffic to deal with (i.e. annoy), I'll zip past people to find an emptier bit of roadway to do this.
Between driving like Miss Daisy and track days that show you there is nothing you can do on the street near what is actually "track fast" I've kept my tickets down to where I can do the online traffic schools to clear them.

Also a scangauge will show average mpg and current mpg at the same time.
Have fun!

I'm getting 14 MPG......
