what kind of performance modification increases power, but also saves gas?

 

loose some weight in the car

 

CAI, exhaust, drop

 

++ and s/c it, my gas milaege remained the same.

 

I seemed to have lost gas mileage when I got the exhaust.
It's not that much, though.

According to my trip meter.. I'm now using 8-9L of gas for every 100km driven vs 7 [pre-exhaust].
This is using cruise control going at 120km/h at almost 2.5k RPM.

This is all based on a one way trip for about a 650KM drive....

 

do you have a 6MT? With a 5AT at 120KMH you should be reving at around 2.25K and should be getting about 33 MPG...

To the OP, you can get better MPG by removing weight from the vehicle. take a look at the TL diet thread started by inaccurate. As well the CAI helps slightly (larger and clean filter). The J-pipe in theory will help out with MPG as it adds 15 WHP/TQ at the lower range of RPMs, so less reving is needed to accelerate at the same rate.

 

+1

 

Yeah I have the 6MT. In 6th I'm around 2.5 [I think, iirc].

Something odd happened... On my way back to Montreal [5 hour drive]. The TL was getting the gas mileage it used to get. 7L/100km/h. I have no clue why suddenly it's getting that mileage again. Maybe it was that B service I had done..

 

Cold air take saved me a ton on gas mileage if you dont stomp on the gas all day long.
