Looking to tune my new to me 14 E63s and am on the fence as to who to use. I had Renntech(full tune) on my 2013 E63 which i sold year ago and was very happy with the performance and reliability but looking at Renntech's site its showing the tune for 91 octane brings the power to roughly 638hp which is really only about a 33hp gain if you go based on real world numbers and not claimed figures. The Eurocharged website is claiming roughly the same but for nearly half the price. My car has the UPD cold air induction kit and from what I read there are some benefits. Since the EC site doesn't specify what's required for stage 2 can anyone provide some more details? My Porsche GTS is stage 2 tuned which included HF Cats and BMC filters. I guess if CA offered 93 octane i wouldn't be writing this but that's not the case and its hard to justify paying $3k for 33hp.

Congrats on the new car! I have a 14 as well and you’re gonna love it.
stage two is mainly downpipes, that’s the main difference between stage 1 and 2.
however, many people upgrade their plugs to a colder range and install higher flow filters while they are at it.

What are the go to DP's for these? Am I right to assume my car has high flow filters since its got the UPD Cold Air Intake Kit?

Call Eurocharged Houston and speak to Sean. If you have E85 in your area make the most of there Flexfuel tune. I'm making 725rwhp before I fitted my UDP cold air intake. I'm doing 100-200kph in 6.2secs!

Research AMS alpha tune as well. They turned my 16 CLS63S into a beast! I also ordered their auxiliary heat exchanger to help reduce heat soak.

I challenge you to find a better HP/$ ratio than the EC flex fuel tune from Jerry at Eurocharged.
Customers are achieving similar quarter mile and 60-130 times with a E85 tune and stock hardware when compared to other tuning houses requiring a bunch of aftermarket parts to achieve the same results.

This car is going to be my DD. How reliable is the tune?

This is my daily driver. Keep up with routine maintenance and you'll be fine.
The tune operates at 18 psi max... and the torque has been retarded down low to protect the drive train.
I'm biased obviously but I think this is the best tune available right now for our platform.
Less boost means less heat, less torque means less stress.

What other tunes have been shown to delivers 10's without the addition of supplemental hardware?

I see you are in SoCal... reach out to Marine_1... he is in California as well and running the tune. He will be able to give you perspective for California that I can't.
