OP: get a tune for the power potential, throttle responsiveness, torque gains, etc.

However, don't get it because you're convinced it makes any sort of fiscal sense due to an MPG improvement. Let's say a tune is $800, and your average post-tune MPG goes up by 2 from 20 to 22. While a nice bump to be sure, the actual fuel savings is less than 2 cents per mile, assuming $4.00 gas. Spending $800 and then saving less than 2c per mile... you'll have to drive 44,000 miles before you recoup the cost of the tune in fuel savings.

I think a few domestic auto manufacturers actually do exactly that (shut down half the cylinders while cruising). It's a great idea.

WOW! Please, let us know what you are doing, that is outstanding!

Ducatic230

Yeah, my GMC does that and at 68 mph I average 24 to 25 mpg. If not in a rush on the highway about 55 to 60 I can get as much as 27. But that is at night when temps are down, oh and i run 89 octane.

I think its about time for me to post my findings since the Powerchip Tune.

For perspective, a little about my driving situation:

• My commute to work Mon-Fri is ~26 miles round trip[22 freeway 4 street]
• Unfortunately living in Orange County, 20 of those miles are spent in bad stop-and-go traffic & I my A/C is running throught the commute
• On the rare occasion where the freeway is moving, or on weekends, I cruise at 75-80mph

I average between 19.5 to 20.5mpg on a tank and if I was to set my cruise to 65 on a flat freeway I top 26mpg. All figures were taken while running on stock 225F/245R Continental Tires







My "before tune" tank MPG never breached 18mpg [under similar driving situations] and doing the same 65mph freeway test never yielded over 24mpg. Of course there is more to the tune than the MPG, but I will stay on topic this this thread.

But lets all be honost and say we've all had one of these MPG moments as well

Mr.Benzo

I would post my post tune mileage numbers but they are no bueno. Its hard to tell it if is my happy feet that are to blame or the fact that I now live two stop lights away from work. Turn car on sit at light, drive two more lights turn car off...since I live in the Tysons area you may feel free to insert lots of traffic at any time of the day.... 13 mpg is my average over the past 500 miles :/

Does the comfort mode greatly reduce your MPG since it starts out in 2nd gear?

Newzchspy

Do you mean increase your MPG since it starts out in second gear?? I use C in the local portion of my driving and haven't seen any difference and I am pretty modded. Also C does not alleviate the "bump" but does help you feel it less.

whatthecrunchyo

The reason I asked that is because it seems like my MPG is around 2 less when I use it (which is rather infrequently). I do enjoy driving in it because it is rather smooth and I can mellow out, but I'm afraid to use it because the thing already eats gas.

Sorry guys I haven't been on. To answer the question about how I get good mileage I'll list the things I've done.
I have a Renntech Airbox with k&ns
I have my second cats and res deleted, with 2.5 or 3 inch pipes, with the x-pipe all the way up front, the material used to do this was stainless steel and I polished the insides myself
I run 255 in the rear and 225 upfront, summer tires.
I weight only 140 lbs most of the time, I gain weight when I don't do my jujitsu
Spare and tools have been taken out, and my car weighs around 3320 pounds with the spare in the back.
Tire pressure is 32-33 psi in front 34-36 psi in the back (can't remember how much but around there)
I'll be taking a trip to Ohio so hopefully if I remember I'll take a pic
My Mazda cx-7 will also be driven so it would be interesting to see the different directly

I recently put the EC tune, 185mm pulley, heat exchanger, coolant separator kit, and Sprintbooster on my car. I monitored it closely aftewards and lost about 1 MPG on average. Not bad for the claimed 40 RWHP, but the tune didn't improve mileage like some said it would.

To be fair, the Sprintbooster may have had more than a little something to do with this because it makes the car a LOT more responsive now, so I can take advantage of more throttle in day to day driving. But I still seriously doubt you're going to pick up any gas mileage. Still, close to the same mileage with noticably more power is a feat, IMHO.

sinister55

you also have a supercharger which makes a big difference when it comes to tuning, the sprintbooster is the main reason it dropped a bit, but the pick up is a lot better

Slater126

The pick up is a lot better to say the least! It's positively explosive now in all driving situations, when it was kind of lazy before unless you really jumped on it.

1 MPG isn't a bad sacrifice for this but again, I'm dubious about the idea that gas mileage will improve with mods. Maybe if you just did the tune, but who realistically does that? If gas mileage is the primary concern, or even a concern, a car like the C32 isn't a good choice. Even on its best day, mine barely clears 22 MPG on the highway. Urban/highway mix is more like 16 MPG. My '11 GTI gets 10 MPG better in the same driving cycle, as did my old RSX Type-S.

sinister55

haha, very true and well put, and another thing is the modding bug... you can never stop it lol
Sorry for going alittle off topic, but how do you like your GTI? I was thinking of getting another car, and it was one of my choices

Slater126

Let me put it to you like this. When I had the C32 and the RSX, the C32 was driven more, by far, despite the major gas mileage penalty. Since I bought the GTI in mid-May, I've put about 200 miles on the C32.

I can't say enough good things about the GTI. Excellent powerband. The 2.0 turbo reminds me a lot of the S52 engine in my old E36 M3. Very torquey at all RPMs and you can barely tell it's a turbo. It also feels rock solid and is very comfortable and well built. And if you can do without leather (and why wouldn't you want those plaid seats, LOL!), navigation, sunroof, etc., as I did, you can get into it for considerably less than 25k.

For this type of car I give it 5/5 stars.

sinister55

wow, I do hear good things about it, but coming from an AMG owner is better lol. Do you have stick or DSG? and if you dont mind me asking is the insurance more expensive than the amg or less?

Slater126

It's a 6-speed manual, 4-door. The DSG was tempting but I like shifting my own gears where possible. And insurance is roughly the same as the AMG.

sinister55

Cool man real nice!!
idk which tranny to get I know the DSG is lightning quick, but stick is always fun. Thats for the info man

ChiCho55AMG

I know it has been 1 year on the last post but couldnt pass over without sharing this on my w209 CLK 55... HAPPY NEW YEAR ALL !

ghiaguy

dang! That's excellent!! Happy New Year!

MBNiko

Doesnt the CLK55 W209 have 200 MPH on the speedo? Or is it different because you're in Lebanon

ChiCho55AMG

Yes it have 200MPH for CLK55 2005-2006 but CLK55 2003-2004 is 160MPH and my car is 2004

ChiCho55AMG

Yea Eurocharged give u power + gas miles better

ghiaguy

Yeah, I love my Eurocharged tune. I wish I had freeway miles on my commute so I could enjoy the mileage

Quickvr4

I tried really hard to get the best gas mileage on my C55 after the Eurocharge tune and got 26.5mpg!! Regular driving it is safe to say you will see an extra 2mpg.
