Stock vs Aftermarket Tune - 1/4 mile performance
Spraying pure or 80+% meth before the turbos has substantial proven gains.

Are there any post-intercooler pipes able to be drilled for the nozzles?

But, the IAT is on the passenger side, just past the intercooler, so if the air from less cooled passenger side hits the sensor before mixing with driver side air, we may be seeing exaggerated IATs then what's actually hitting cylinders




I'm glad you've found benefit from the thread. Getting a 50% on registration is no joke. Congrats on that.
I've seen Jerry's car and his E85 dyno plots. I do not know if he is running the same base tune as I am. I do know he is running HF Cats while mine are stock. I run water meth for Air Charge cooling... he has the AWS cooling system which performs very well at maintaining intake temps during the run; much better than my water meth setup by the way.
Finally, I'm running the stock fuel pump while he has upgraded his to a different one. That's the secret sauce right there.
I confident in saying he has the record for horsepower on stock turbos now.
After fueling. his biggest hurdle was reigning in low end torque. The TCU management system gets a little pissy when you throw north of 800 AWTQ at it.
He has been running straight E85 for a couple of months now
If you end up running E85 you will be a terror on the highway. The top end power is unreal now.
I'm at 680AWHP now around 5500 rpm... Jerry bests me by at least 30 more WHP peak...
Regarding your transmission, have you had it re-adapted? This may help your case somewhat.
I recently did a transmission flush and software update as a preventative measure as well.
I can't say I've experienced what you are describing so i can't comment more.
If you end up getting the tune, please come back in and post up your experiences. I'd love to hear about them.
I've got quite a few questions I'd like to ask about a number of things.

Mine cost me $400.00 as I was out of warranty. I also received the friends and family discount though. I suggest reaching out to your local dealership service adviser to discuss.
After the update they have to drive the car for a set amount of time in varying driving conditions to re adapt the transmission. This is critical and will also add to the overall cost of the reflash.
Feel free to PM me with any questions you may have.

I'm not at liberty to disclose Jerrys runs, but I can tell you his IATs only increased by 10 degrees F over the course of the run, and the temps rapidly dropped back after the run. In contrast, using the water meth, my runs went from a similar resting temp and increased 26 degrees during the run... temps took longer to come down as well. This stands to reason though because I only get the cooling effect when spraying during boost. Off boost, no spray, no help with temps.
I'm giving serious consideration to augmenting my car with this kit after seeing his logs... the kit works....

I know they've been willing to do group buys in the past, which is how I got my Audi setup.
I'm an engineer by profession and I like documenting my progress for other peoples benefit.
I also feel there is way to much smoke and mirrors in the aftermarket world. Transparency is key with me.
We have been slowly tweaking this tune over the last year.
Jerry liked the performance so much he ended up buying a E63S of his own. He is on the same tune as me, but he is looking to additional hardware mods to truly explore the upper boundaries of these cars.
As before, I think my tune will end up being the stage 1 version of this flex tune, and for those of us who want a true E85 tune, with simple hardware mods Jerry should be able to get you there.
Look to this thread for a dyno plot of the results of Jerrys efforts to run full E85...
