Put a turbo on it..

Yeeeeeaaaaaah-

And a roots supercharger!

Speaking of tyre pressure, what should my GTI normally be at? I couldn't find where it says what the recommended psi should be. I have it at 34 and my fuel consumption seems a bit high. I average around 10.5L from Mon - Fri through 2 hours of traffic to and from work each day with 2 people in the car.

for a 45 series tyre I usually run at 38Psi .

I don't mean to be a prick, but if you want more power and less fuel use then the 2.0FSI is the wrong car for you.

philthy is right, the most effective way to achieve your goal is to get another car. A Mk6 118TSI or used Mk5 GTI / 2.0 TDI would be good places to start.

Granted Canberra traffic is a lighter than Syd traffic but over the last 18 months or so our GTI's average consumption is 8.9l/100km.

my ave. is 8.8 to 9L per 100km, i just drive to and from work. am i asking too much? my right foot is pretty gentle.

Let's assume you travel 15,000km each year and you save 1L per 100km by investing $1500 in ECU mods etc. Assuming petrol is $1.40 a litre you're only saving $210 per year so that's nearly 7 years to pay it back.

You would be better off running a premium fuel in the car (98 octane - BP ultimate) and you should see an improvement. The extra cost is only $135 a year but you should be able to save double that from increased mileage assuming that you're not running decent fuel already.

As G-Rig said make sure you have the tyres inflated above the recommended comfort levels.

I have a tune and I have not seen an improvement in fuel economy.

thats coz you have APR

thats coz you have APR

A truly worthless post!

he took it..

Hmmm..... Well if GIAC weren't behind the times and released a tune for a power plant that's been in the market for the last 3-4 years maybe I would have considered them....

I just can't see how you can gain performance and gain better fuel economy... The 118TSI is a good example, VW de-tuned the motor to get better fuel economy out of it..

fuel economony

i take my foot off the accelerator pedal , it seems to work. The ECU flash just helped use the accelerator more. No real economy gains

If people want more power most wouldn't be retuning for better economy. It's also hard to drive more sedately after a reflash.

I'd get a 1.4TSI if you're worried about getting the best economy.
