I don't know if the car is just breaking in, or if it's a result of the modifications (Hahn IC, catless open DP, my hpt tune) but this car is now getting amazing gas mileage! I noticed a big chang when going catless.
The car used to do about 26-28mpg. Last two tanks have been 30mpg, that includes on-ramp fun and 100mph+ freeway pulls. That's about 1/3 back road and 2/3 highway. This tank I've been going a little easier, and the trip is indicating i should get closer to 35mpg (460-ish miles on the tank). Wonder what it would to if i stay out of boost for a whole tank? Who needs a Prius?? lol. I <3 direct injection and this car
Cliffnotes - you don't have to sacrifice performance for economy, just get yourself and LNF

I call BS, there is no road in Berks County capable of 100mph without death by catapult out of seat.
Awesome mpg though, reminds me of why I hate my cav once again,
I get 23... at best... but mine sounds better so ha!
But really, that's awesome and rather impressive!
i saw your profile says 320hp, is that on the current setup and tune? if so, that's awesome fuel economy, especially for the amount of performance you're getting out of it.
Check out my build thread!
Are you going by the DIC for those averages or calculating at the pump?
not surprising

I don't really pay attention to the milleage on my Solstice.
I can't complain.
The low compression and small displacement go a long way with milleage. DI surely adds benefit.

maybe in a lowered cav - kappa's hold the road

Airflow readings indicate about 320-ish hp. never dynoed, but readings are constant with others with similar mods/boost

Calculating at the pump - only way to be accurate. miles since last complete fill up divided by gallons for complete fill up. Did 32mpg on the last tank. DIC average was at 30.8, but it's a long running average. I haven't figured out if it clears memory after a certain amount of miles/time or just keeps averaging until the user resets

eco FTW!!
it will go until the user resets. it is a lifetime average if it is the same system as my trailblazer
my 97 sunfire gets 30 mpg and is a 3 speed auto.

lol and i once got 42 mpg with my 2002 LN2, but neither of these cars made ~300hp.
Last tank was a solid 32mpg on the solstice
You don't need much power to cruise.
LNF kappas with tunes are getting amazing milleage. regardeless of hardware mods.
I should start logging my milleage.
It's a great example of how cats are not entirely cost efective, especially in lean running clean burning DI cars.
