Do we have a dual pulley option like the S4?

Reading up in the S4 forums.
Does the C7 3.0T A6 have the dual pulley option and tuners have a file for it?

I don't think any of the tuners have a specific file for that at this point.

C7 A7 here. I have an OD pulley waiting to be installed. From reading the B8 threads, it looks like GIAC has the best off the shelf tune for dual pulley. I have a good feeling all of the tuners will have a dual pulley file in the next 3-4 months, however the B8 S4 box codes will probably go first.

I would like to see the OD pulley for the C7 3.0t come to fruition, plus flex fuel sensor and tuning maps, and maybe a down pipe that makes proven power. That *might* be enough extra HP for me to consider not getting into an S6 this year.

I just had my ATI (GMG) overdrive pulley installed today! My current setup now is Ijen intake, magnaflow exhaust, awe dps, GIAC stage 2 and the ATI OD pulley.

Initial impressions are like what others have posted. Definitely more torque and hp throughout the band, similar from going stage 1 to stage 2. I don't have any logs or timeslips yet, but plan on taking a trip to the track in the next few weeks.

Also props to Danny at HTL motorsport for the install. He did a great job at a great price.

So, there is no change on the tune?

Not yet, same stage 2 file for now.

Did you log the car to see if it's running safely?

Technically, the only company with a true dual pulley file even for the S4 is EPL. If you want to run dual pulleys and keep the bypass valve closed you need to either see if EPL has a file for you or you can stack Chipwerke on top of your stage 2 tune like Loe did who just ran an 11.2 in his S4.

I have a custom crank pulley coming hopefully soon that i'll be beta testing the DTUK on.

I'm actually switching from GIAC to epl. The dual pulley e85 tune is in the works right now. I just installed the autotech hpfp this morning. I ran the car for about 200 miles on about 80% e85 this morning and only threw a lean code once. No big deal really just cleared it and hasn't come up since. Even without the full e85 tune, running the car with dual pulleys, a lot of e85, and epl 91 oct tune, the car has way more low end torque than it it did with the stage 2 Giac.

What is needed to run the e85 blend? The hpfp?
What bar sc pulley do you run?
Does your car run hotter than before? Did you upgrade your cooling?

Do you mind posting the cost of the gmg crank pulley or pm it to me.

Just the hpfp to run full e85. I ran 50/50 e85/91 on the stock hpfp without any issues. Stock cooling for now. Haven't logged the car much so I can't answer the rest.

The GMG cp is a bit expensive (like to the tune of $900) but i'm sure well worth it. You can get a single piece one from JHM for under $500. You can get a custom one for about that price or if you have a good machine shop in town you could have one made for less.

I'd recommend running no more than 30% e85 with the stock HPFP. If you are having to clear lean codes it means the car was running lean. No need to risk something like that. Seems most people are getting stable afr with 30% or less though.

Thank you both for your feedback.
