Hi Everybody,

I have decide to keep a build/progress thread for my 2015 Macan Turbo.

Took the car to Garage Auto Sports in Newmarket, Ontario. Bill and his crew have been taking care of my cars for the last 10 years.

They have a 4WD Mustang dyno so naturally we had to get some baseline runs & add a stage 1 flash. I went with Bill's custom tune, he knows I'm not easy on my cars so he makes sure they can take the abuse.

Garage Auto Sports been tuning Euro cars since 2015 and Bill has been tuning personally for about 10 years

I am very pleased with the numbers we have achieved so far. All runs were done on Petro 94.

Dyno Runs:

Future/upcoming mods:

• Flat6 filters
• GAS Stage 1 PDK Flash
• GAS Water/Meth kit (they have a custom Q5 tank that's a direct fit for the Macan)
• Downpipes & Stage 2 re-tune
• Lowering links

Huge gains man…congrats!
So glad to find this excellent tuner so close! Cheers !

I'm not familiar with GAS, and wasn't aware there was a PDK tune for this platform. Can you share a link?

you are doing it the right way…getting baseline numbers down first etc. Nice numbers. If I may ask why a water meth system? Was the tuner hearing a lot of knock?

 

[AlucardNYC]

So he can run a more aggressive tune

I apologize for a dumb question. Who or what is GAS? I’m familiar with Cobb, APR, GIAC and others. But I’ve never heard of GAS.

 

[AlucardNYC]

Your setup and numbers of your Turbo compared to my S with my setup and numbers show a substantial difference in cap, and I didn’t think displacement would be this much of a factor. In terms of maximizing power, this justifies buying the Turbo model 100% and the GTS, not so much.

I’m a 361whp / 467wtq
2016 S (intake, exhaust, intercoolers, Cobb protune)

vs.

Yours 400whp / 500wtq
2015 Turbo (Cobb Protune)

Thanks Terry. Check him out some time

Couple reasons for the water/meth:

- IATs were getting hot after a few pulls. Water & Meth is an easyway to keep things cooler. I'll be getting the AMS intercoolers too.

- Helps keep the intake valves clean so hopefully no need for intake off valve cleaning. (Former BMW owner, call me paranoid lol)

- And as Alucard said a more aggressive tune.

I'm hoping to have a highboost tune that will activate the meth system via the sport+ button, so I can run a regular 91 tune in normal & sport mode . We shall see if this can be done

No such thing as a dumb question Bruce.

GAS is a local perfomance shop up here in Ontario l, Canada. All of Bill's tunes are made inhouse.

I'll see if I can get him to join and become a board sponsor.

I didn't realize there would be that much of a difference. I'm sure your car is a blast to drive. What intercoolers are you running?

I'm not using the Cobb flasher.

I’m running AMS Intercoolers.
What do you use for tuning?

Thank you for the education.

The benefits of meth are undeniable:

• allows you to tune more aggressively if desired without running into knock situations
• even without tuning you can see big gains on regular pump gas files. This is normally the path we take, since it doesn’t put the engine in a dangerous position if the tank were to run dry. Gains of 20-30hp are normal with no re-tuning on a 6 cylinder, with 80-100hp gains seen on turbo V8s due to massive drops in intake temp and therefore a denser air charge (I personally saw a 60 degree Celsius IAT drop on our Audi S7)
• water meth continuously cleans the intake tract, reversing the effects of direct injection carbon buildup. Pulling the intake shows spotless intake ports and combustion chambers after a short period of use. This means that even if you’re not after any power gains, you can still see large benefits to fuel mileage and huge maintenance cost savings
• a proper quantity of injected meth is enough to bring pump gas up to around 106 octane

(This is not an endorsement of any brand kit in particular, but on the system as a whole)

We didn’t see any knock correction at all on John’s Turbo even without meth. The tune is still very conservative to counteract his Stig-like driving manners I’m sure John will be posting gains once the meth kit is installed!

We don’t use retail-based tuning platforms like Cobb, etc. All of our software is developed in-house using hardware and software combos that allow us full unobstructed access to the ECU’s internal memory areas. We use OEM documentation and data logging to modify the data areas.

The Porsche SDI10 ECU is very similar to what the supercharged Audi 3.0T and VW 2.0T use, so developing this chassis was a logical next step for us

Hello GASBill,
Welcome and thanks for the Meth education Like others, also curious on the PDK flash.
John has turned me your way........looking forward to a visit soon....you are local to me
Happy Thanksgiving !

Thanks for taking time to explain Bill.

Happy Thanks giving.

Thanks for the reply Bill. I understand the benefits from water meth and it can be a great addition to any modified engine. You are exactly right about reducing not only intake air temps but also the charge temp ( the actual temp of the homogeneous air/ fuel within the combustion chamber). It can also guarantee an increased octane level just as you said.All of those benefits means the engine engine does not have to pull timing because of increased intake temps or lower octane fuel. Allowing more advanced timing is what gives the engine more power. Proper tuning is required and it sounds like y’all have a lot of experience with that. Kudo’s.
Some people may want to install one without tuning for more power because of the cleaning …as you also stated. If you do tune for more power with water meth then it becomes a little more tricky. Making sure all cylinders get an equal amount etc etc. I mention this because some may be thinking of a diy install. I caution those that are….educate yourself before doing this. I have ran a water meth system in another car for years. On track and off. Mine was m.a.f. triggered. I learned a lot.
can you share where the nozzle or nozzles are and their size. Delivery rate?..progressive or linear? Sorry..this may be your secret and I understand if you rather not.

No problem at all!

As stated, we have not installed a WMI system as of yet on the Macan platform, but we will likely do so through the use of a machined throttle body spacer, or we may end up building a set of charge pipes & throttle body transition to accommodate a set of nozzles. I’ll update you guys with what we come up with for that one! There’s always somewhere to mount a nozzle, even without special parts.

You’re absolutely right about the safety aspect of tuning for meth, although with the proper safeties in place (such as a properly set up level sensor and solenoid) it’s a very safe way to reach your goals. Regardless, we generally like to tune with the WMI system turned off unless requested by the client, and we always monitor AFRs and correction closely to ensure safety under all conditions. As far as nozzle size, all of the WMI manufacturers have a chart based on power level like this one:

If you’re simply running meth for cleaning purposes, a smaller nozzle will do fine.
